On the first day of school, transfer student Song Chi and top student Gu Yan were in tit-for-tat confrontation for the first time. Song Chi declared war on Gu Yan in public to break his undefeated record of being "number one in the city".
Early the next morning, Gu Yan was attacked and suffered serious eye injuries. However, Song Chi unexpectedly showed up at the hospital to save him. He also revealed that the attacker was his twin brother, clearing his suspicions, and the relationship between the two quietly eased.
As the relationship deepened, Gu Yan gradually discovered the gentleness under Song Chi's unruly appearance. Song Chi was also attracted by Gu Yan's calmness, and they changed from competing with each other to relying on each other.
After the course, Gu Yan forcibly took Song Chi back to his residence to live together on the grounds that he was "lack of a chef". On the way, he was bumped into by a classmate, which sparked a heated discussion. While the two were fighting and making fun, their relationship gradually heated up and developed towards a closer relationship.
