Yu Nuannuan and Chen Qinghe are less than one year apart.
Yu Nuannuan's grandfather and Chen Qinghe's grandfather were family friends, so Chen Qinghe became Yu Nuannuan's younger brother.
They had played together since childhood, and during adolescence, Chen Qinghe developed a different affection for Yu Nuannuan.
She was a sister, and he didn't want to be a brother, but he used his identity as a brother to say a lot of things he wanted to say and do a lot of things he wanted to do. The elders said that the relationship between the siblings was very good, but he knew that he never treated her as simply as a sister.
Until they graduated from college and worked together in other places, he tried every means to share a room with her and planned step by step to make her his lover.
