Sibling Love Between the Gentle Uncle and the Tsundere Girl

The male protagonist's name is Ye Feng. He went to work with an agency and met a cute little girl from the same place as him. The little cutie is a 19-year-old girl named Ruobing, but she is petite and has a soft and cute appearance that is very deceptive. She is older than most boys and girls on this journey. Because the bus took most of the people to the front and the agent drove behind, it happened that only the little lolita was still active in the group chat. The agent happened to ask Ye Feng to add Ruobing on WeChat for easy contact. The gentle and calm boy Ye Feng meets the cute Ruo Bing. After they add each other on WeChat, what kind of sparks will collide between them?
