Oh No! My Little Sister Has Won Me Over

This book tells a story about waiting. Seventeen-year-old Xu Miao broke into He Qing's life on a rainy night, and spent seven years going from direct confession to separation in a foreign country to returning to her again. There was no vigorous vow of eternal love, only a cup of soy milk, a pot of meat, a piece of paper saying "eat", and countless quiet late nights. He Qing is a mountain that has been frozen for many years, and Xu Miao is the person who is willing to sit at the foot of the mountain and wait for spring. In the end, the mountain did not melt, but new shoots grew in the cracks on the mountain.

The relationship between the two is delicate, tugging, and establishing their feelings step by step. If it's not enough, please update it quickly.
