Say I Love You Manga Volumes: Full 18-Volume Guide

How Many Say I Love You Manga Volumes Are There?

Here’s the bottom line: Say I Love You. (好きっていいなよ。— the original Japanese title) is a finished manga series with 18 volumes and 72 chapters, all available in English. Each volume collects several chapters, so those 72 chapters are spread across the 18 books. You can read the entire story from start to finish right now — no waiting for future releases, no cliffhangers left dangling.

The series was written and illustrated by Kanae Hazuki (葉月かなえ — the Japanese spelling of her name) and originally ran in Dessert magazine from February 2008 to July 2017 (the final collected tankōbon volume shipped in September 2017). Dessert is a Japanese manga anthology — a magazine that publishes individual chapters from many different series on a regular schedule, which are later collected into the paperback volumes you buy. That nearly decade-long run gave Hazuki plenty of room to develop her characters without rushing.

Say I Love You. is a shoujo manga, which simply means it was originally published for a teen-girl audience. The genre is known for focusing on emotions, relationships, and personal growth — and this series is a great example of all three.

The story centers on Mei Tachibana, a high school girl who has completely shut herself off from friendships and relationships after being hurt in the past. She doesn’t trust anyone. Then Yamato Kurosawa — the most popular guy in school — takes an unexpected interest in her, and Mei’s carefully constructed walls start to crack. What follows is a slow-build romance grounded in trust, vulnerability, and the messy reality of opening yourself up to another person.

For collectors, the completeness factor is a huge plus. There’s nothing worse than falling in love with a series only to find out it’s been put on hold indefinitely or the English translation stopped halfway through. With Say I Love You., what you see is what you get: 18 volumes, one complete story, beginning to end.

Is This Series Right for You?

Before you commit to 18 volumes, it helps to know whether this manga matches your taste. Here’s who will get the most out of Say I Love You.:

• You love realistic high school romance with emotional depth. This isn’t a fantasy world or a gag-driven comedy. It’s a grounded story about real feelings, insecurities, and the slow process of learning to trust someone. If that sounds appealing, this series delivers it beautifully.

• You prefer slow-burn relationships. The term “slow burn” means the romance builds gradually over time rather than happening all at once. Mei and Yamato’s relationship develops step by step across all 18 volumes — with setbacks, miscommunications, and small victories along the way.

• You’re new to shoujo manga. Say I Love You. is a genuinely great entry point for the genre. The storytelling is straightforward, Mei is a relatable heroine, and the 18-volume length is substantial enough to feel satisfying without being intimidatingly long.

• You want a complete series. No waiting, no uncertainty. Buy all 18 volumes and you have the whole story.

On the other hand, this might not be your series if you’re looking for fast-paced action-romance, fantasy elements, supernatural twists, or heavy comedy. Say I Love You. is a slice-of-life romance through and through — meaning it focuses on everyday experiences and quiet personal moments rather than dramatic plot twists or larger-than-life scenarios. It’s introspective and emotionally driven. If that’s not your speed, there are plenty of other great romance manga out there — but this one knows exactly what it is, and it does it well.

The Easiest Way to Collect Every Volume

Let’s talk about the practical side of getting all 18 volumes on your shelf (physical or digital). In terms of pricing, each volume falls within the standard range you’d expect for a single manga volume at retail — so you can mentally budget for 18 individual books at typical manga pricing when planning your collection.

Digital: The Most Reliable Path

If you want the smoothest collecting experience, digital editions are the way to go. All 18 volumes are available as official Kodansha digital editions. Kodansha is the publisher that handles both the original Japanese release and the official English translation, so their name on a volume means you’re getting the real thing. Digital volumes are available through major platforms like Amazon’s Kindle store, Apple Books, Kobo, and Google Play, among others.

Going digital means no hunting for out-of-stock printings and no worrying about condition. You can build your complete collection in a single shopping session. Digital editions also tend to be easier on the wallet since there’s no printing, shipping, or warehousing involved — the per-volume cost is typically lower than physical copies at list price.

Physical: Beautiful but Requires Patience

The English physical volumes were published by Kodansha, and they look great on a shelf — the cover art is lovely and consistent across all 18 spines. However, since the series wrapped up years ago, availability of individual print volumes can vary. Some volumes may be easy to find at regular retail through bookstores and online retailers, while others might require a bit more searching.

There is no omnibus edition or box set that has been widely released for this series. An omnibus would be a single larger book combining several volumes into one — but since none exists here, you’re collecting individual single volumes one at a time. For an 18-volume series, this is completely manageable, but it does mean you can’t grab one big box and be done with it.

If you’re set on physical copies, check availability across multiple retailers — major online bookstores, your local comic shop, and secondhand booksellers are all good places to look. If a particular volume proves elusive in print, remember that you can always fill the gap digitally — a mixed collection is better than an incomplete one.

Volume-by-Volume Overview

One of the best things about Say I Love You. is that it has a clear emotional progression — the story doesn’t just meander. Mei grows as a person across all 18 volumes, and each section of the series has its own distinct feel. Here’s a roadmap so you know what you’re getting into.

Volumes 1–3 — Mei Opens Up

Volume 1 is where everything begins, and it does a wonderful job establishing why Mei is the way she is. She’s not just “the quiet girl” as a shallow character trait — Hazuki gives you real reasons for Mei’s isolation, and you feel the weight of it. When Yamato enters her life, it doesn’t feel like a fairy tale. It feels awkward and uncertain, which is exactly right.

Volumes 2 and 3 develop the central relationship at a pace that feels earned rather than rushed. Mei doesn’t suddenly transform into a social butterfly because a cute boy likes her. Instead, she takes small, tentative steps — letting her guard down a little, then pulling back, then trying again. These early volumes establish the emotional tone of the entire series.

Here’s the honest test: if you connect with Mei by the end of Volume 3, you’re going to love the rest of this series. Her journey is the beating heart of the story, and these first three volumes tell you exactly what kind of manga this is — quiet, emotionally honest, and deeply empathetic.

Volumes 4–6 — Jealousy and Growing Pains

This is where Say I Love You. starts complicating things in the best way. New characters enter the picture, and suddenly Mei and Yamato’s relationship isn’t just about the two of them anymore. Jealousy and rivalry become real tensions — not in a melodramatic love-triangle way, but in a way that feels true to how insecurity actually works in relationships.

What elevates these volumes is that Hazuki doesn’t limit her story to romance. Themes of friendship and self-worth start weaving through the narrative. Mei isn’t just learning how to be someone’s girlfriend — she’s learning how to be a person who lets others in, period. The supporting cast gets more developed here too, and you start to see that this is a story about an entire social world, not just one couple.

Volumes 7–12 — The Long Middle

Six volumes is a big chunk of any 18-volume series, and this section will hit differently depending on what you’re looking for. The middle stretch of Say I Love You. broadens the lens significantly. Multiple side romances and supporting character storylines get real page time, and some volumes focus more on the extended cast than on Mei and Yamato directly.

If you’re the kind of reader who only cares about the main couple and wants every chapter to advance their relationship, this section might feel slow at times. But if you enjoy watching an entire cast of characters grow and change — seeing how different people handle love, friendship, jealousy, and self-doubt — these volumes are genuinely rewarding. Most readers who stick with this stretch find that the investment pays off when the final volumes pull everything together.

Mei’s personal growth becomes arguably more important than her relationship with Yamato during this stretch. She starts making real friendships, figuring out what she wants beyond just having a boyfriend, and developing into a more confident person. It’s not flashy, but it’s the kind of character development that makes the eventual payoff feel earned.

Patient readers who invest in the full cast will find that these middle volumes add real depth to the story’s conclusion. The series is stronger because it doesn’t rush to the finish line.

Volumes 13–18 — Resolution

The final six volumes bring everything together. The central relationship between Mei and Yamato moves toward its conclusion, and the various threads that Hazuki has been weaving throughout the series start converging. Without spoiling specifics, the ending is satisfying — it feels like a natural destination for these characters rather than a forced happy ending or a dramatic last-minute twist.

Volume 18 is the final volume. The story is conclusively finished. There’s no sequel hook, no “to be continued,” no dangling plot thread designed to set up a spin-off. When you close Volume 18, you’ve read the complete story that Kanae Hazuki set out to tell. For collectors, that sense of closure is part of what makes this series so appealing to own.

Watch Out for These Collecting Pitfalls

Before you start buying, here are a few things worth knowing so you don’t waste money or end up frustrated.

• Out-of-print pricing on physical volumes. Since the series ended years ago, some individual physical volumes may be harder to find at their original retail price. If you see a volume listed for significantly more than the standard manga price, that’s a reseller markup — a third-party seller charging extra because the book is scarce, not what the publisher intended it to cost. Be patient, check multiple retailers, or consider digital for those hard-to-find volumes.

• Make sure you’re buying the correct edition. You want the official Kodansha English edition. Don’t confuse these with fan translations — unofficial versions translated by volunteer readers and distributed online, which are not licensed or authorized by the publisher. The official volumes will clearly show the Kodansha logo and have consistent cover design across all 18 books.

• Digital sidesteps all availability headaches. This is worth repeating: if you’re having trouble tracking down specific physical volumes, the digital editions are always available and always at their standard price. A complete digital collection is just as valid as a physical one.

Will Your Collection Stay Complete?

This is a question that matters more than people think. Nothing’s more frustrating than proudly finishing a manga collection only to learn that a sequel series, bonus volume, or “part two” has been announced that makes your “complete” set suddenly incomplete.

With Say I Love You., you’re safe. The main manga story concluded in 2017 with Volume 18, and that narrative is complete. One additional volume — a digital-only bonus release in Japan — was published in August 2022, but it has not been licensed in English. Kanae Hazuki has moved on to other works since the series ended. For English-language collectors, the 18-volume set is the complete story.

It’s also worth knowing that a TV anime adaptation exists — anime being the animated version of a manga, produced as a show you can watch. The Say I Love You. anime covers a portion of the manga’s storyline, so manga readers will get significantly more content. But the anime can be a nice companion piece if you want to see the characters animated, or a way to sample the story before committing to all 18 volumes. It may be available on streaming platforms — check current availability, as licensing rights for older anime series can change over time.

Eighteen volumes. One complete story. A heroine worth rooting for. If that sounds like your kind of read, you really can’t go wrong here.
