[spoiler]I have read a manga before about a boy who asked his crush out at the beginning of the manga, but it doesn’t work out because she is just using him. This leads to one of his now ex’s friend asking him out and they end up dating for the rest of the manga. It also adds that the town thinks the girl is a liar because she sent her dad to jail because he was abusing her as a child. It also ends with the boys brother being stabbed by the dad who became a stalker once he got out of jail.
Sorry I can’t be more specific but any help is appreciated.
