Following Ichikawa Kyoutarou, a teenage boy belonging to the very bottom caste of his school, this work details his troubled interactions with a certain classmate, and his attempt to hide murderous impulses that find themselves in the darkest recesses of his soul. In reality, though, it's a sweet youth rom-com between a messed up boy and a bright, if somewhat strange, beautiful girl. ___ **Awards:** - Won the 2020 Next Manga Award in the Web category. - Was nominated for the 2020 and 2021 Manga Taishou Award. - Won the top prize of the 2021 Tsutaya Comic Awards. **Additional Links:** - [Official X](https://x.com/boku__yaba)
