flowerss's manga / #Manga(2)

heard it from tiktok that chainsaw man suggested this ML has black hair and beated up a girl that interacted with MC then ML was taken to the authorities and MC never saw him again MC is a councillor and listens to ppl then ML came back, and he killed (maybe) a girl the MC slept with bc she was suicidal back then and MV thought the best way was to sleep with them bc he heard it from someone anyways idk if girlie died bc she got her head bashed in the wall
