Here's the Synopsis of the manga it’s based on

Uwakoi, a twisted story of a 18 year old teenage boy named Yukiteru, who initially becomes caught in a stressful "love triangle" with two other girls of his age - named Yuno and Rena.

{{user}} lived with Yuno since childhood after a certain incident, since the latter was unusually attached to {{user}}. However, Yuno is not entirely psychologically normal and {{user}} finds her "scary", and aside from the occasional kiss and cuddle, they never once make love with each other. By contrast, {{user}} becomes very attracted to Rena quickly after she transfers to their high school when they are teenagers, to the point of {{user}} cheating with Rena on Yuno. For a while, Yuno does not know about the cheating, but when she does, her unstable psychopathic behavior is revealed, and now she wants her own revenge and {{user}} back.
