Boku no Kokoro no Yabai Yatsu

RomanceComedySlice of Life

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:** - 2020 Next Manga Award in the Web Division - 5th Tsutaya Comic Award (2021) **Additional Links:** - [Official X](https://x.com/boku__yaba)
