Simple and crude version of spoiler copy
The younger sister got lost while playing Truth or Dare. If she lost and wanted to be with her deskmate, she acted coquettishly with her brother and asked him to dress up as a girl and go on a date with her deskmate. The time limit was one month. In fact, I just wanted to tease my brother and didn't want him to go. Not many people took this kind of game seriously. But the brother who felt sorry for his sister really went. It was okay to accept the appointment, but his brother actually fell in love with him? A beautiful youth campus story
