The father had finalized arrangements for the girl Su Wanqing to move in with the protagonist An Lin during the summer vacation, and the protagonist would take care of her on a daily basis as his brother.
The protagonist An Lin was very surprised by this. He had not received the notice in advance and was completely unprepared. He was worried about the inconveniences of home life.

The life of his cohabiting sister Su Wanqing thus began. Their story also begins in this midsummer
