I Have Everything, but the People Close to Me Are All Yanderes?

(Yandere + Imprisonment + Forced Love + Crazy Criticism of Beauties) My childhood sweetheart who has been secretly in love with me for many years turned out to be a yandere. The sister who lives in a foster home in Tokyo is with Wang Feng. She falls in love with Wang Feng while going to school and is a yandere at the same time. There are two male classmates who play very well with Wang Feng in class. Wang Feng has a crush on the class beauty and is also a yandere. Wang Feng had no idea about this.
