Bai Yueguang Is by My Side

The female protagonist fell in love with the male protagonist at first sight in junior high school. She had a secret crush on the male protagonist for many years without any interaction. It was not until the second year of high school that the male protagonist transferred to the female protagonist's class and became her roommate. The two interacted and gradually became familiar with each other. Not long after they got together, they broke up due to distance. This is HE. Only the middle chapters of the off-site part are a bit sad, the rest are sweet.
