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.

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

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 ...

Preliminary (104/? eps)
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 ...
