Boku no Kokoro no Yabai Yatsu (The Dangers in My Heart)

Kyoutaro Ichikawa may look like your average middle school student, but in his heart, he dreams of murder. Thus, it is no surprise that the one he wants to kill the most is never far off from his mind: the class idol, Anna Yamada.

Reading alone in his beloved school library, he inadvertently begins to rendezvous with Yamada, who comes to secretly gorge on her beloved candies and sweets. Through their interactions, Ichikawa discovers just how much of a ditz Yamada is, and cannot help but support her from the sidelines. Meanwhile, Yamada herself cannot help but tease Ichikawa relentlessly due to his flustered reactions.

With an array of heartwarming daily interactions, the distant bond between the two grows into something more than just library acquaintances. Perhaps, in time, Ichikawa will come to realize that his murderous desires have turned into something else entirely.

Preliminary (145/? eps)

The anime really did an excellent job adapting this manga thanks to its art, direction, and music.

They improved scenes and added other originals that in my opinion turned out better, however the extra content of the play and comedy that the original manga handles is lost a bit, it's a shame.

Let's talk about the premise, which in itself is misleading and a necessary evil in my opinion, although romance is not my favorite genre, I must admit that this anime/manga really left me fascinated, the interactions of the main protagonists at the beginning of the work, that awkwardness/embarrassment and development that they handle throughout the ...

Mixed Feelings

Preliminary (30/? eps)

This manga got an anime adaptation not too long ago, and I got absolutely hooked on it. So much so that I couldn't wait for the episodes to come out, so I decided to read ahead in the manga. As I read the manga, however, I started to slowly fall out of love with the story. Whenever the new episodes of the anime came out however, I was once again in love with it. There are a lot of people out there who defend mangas over their anime counterparts, but I'mma be real here, I think the anime elevates this story a heck of a ... lot.

I am aware that pretty much everything the anime does the manga does too, it is the source material after all, but what the anime does is it focuses the pacing, and adds a few details here and there that make the story feel cohesive. I get frustrated by romance stories that never go anywhere, which is why I was drawn to this series in the first place. It has a sense of progression. I find the manga has a lot of fluff that bogs down this sense of progression, especially with it's little bonus chapters that they sprinkle in constantly. They're all fun to read, but at the same time they feel pretty much tonally indistinguishable from the chapters that actually do matter. There's often a feeling in romance stories that revert to the status quo of hanging threads being unanswered, which I really dislike. Like, something happens between the characters and there's a moment of ooooo I wonder how they're gonna resolve this tension and then.... it just tangents onto something else and we forget the prior thing ever happened. This is my biggest complaint with stories like komi can't communicate (but let's get back to the focus at hand). The problem with the pacing of the manga is there's a lot of padding, and various plot threads feel like they go unanswered for a little longer than you'd expect, even in actual full chapters sometimes. There's an episodic feel to things with occasional continuity, which can be a little frustrating. What the anime does is it cleans things up, and rearranges some of the events in a way that makes them actually feel like they are cohesively flowing into each other, day by day. That was the biggest reason the anime even stood out to me, is there never felt like a moment where the continuity just got reset. There were also occasional details that were modified in the anime that I felt better suited the character developments. Generally I just find the progression in the manga a little haphazard in comparison. I ended up dropping the manga around episode 8 in the anime's continuity (I think it was either ch30 or 40, somewhere around there) in favor of experiencing the show blind, because I felt like it executed everything better, and I plan to do the same with its season 2. If you are someone who is interested in watching the anime, I'd say watch that instead, and if you have seen it and want a little more content between these two, the manga does have the advent of having the extra little bonus content in its bonus chapters, but it's nothing you haven't seen elsewhere, so idk, it's up to you if you read it.

Also somewhat unrelated complaint with the manga, but it has a decent amount of somewhat creepy art of Yamada. Like, when Yamada is being romanticized/sexualized from the perspective of Ichikawa, it makes sense because that's from his perspective. But the manga has a lot of non-canon panels that feel more like pandering for the audience and... need I remind you all that Yamada is a middle schooler? This kinda made the whole manga reading experience a lot more uncomfortable, and I couldn't end a review on it without at least mentioning it

I can't decide between a 6 or a 7/10, but I'm leaning 6 just cause it's okay, but there's a better version out there in my opinion. However, I cannot deny that the manga came first and did write the baseline for a story that I really enjoy. To those of you manga fans of this one, if you like this one I can totally see why. It does have a lot going for it, it's just not my preference.

It was fun… at first. "Psychological thriller" quickly turned oddball romantic comedy was a welcome change for most, and the series quickly found its place among modern rom-coms with a relatable protagonist and steady relationship growth. At some point, I figured they'd soon acknowledge their relationship and start dating, with the series establishing itself as one of the few well-paced romance manga out there.

That point was two years ago.

Now, the manga feels like Zeno's paradox in practice: every two weeks a new chapter comes out and their relationship makes half as much progress as last week's, getting so close to but never actually reaching ...
