Dong Yuxiao is an upright straight man with a youthful life in high school. However, he never expected that his rival and crush would be him. Later, he would be swayed by the domineering school boy. He thought he could finally live in peace, but an ex-boyfriend and ex-girlfriend showed up along the way. On campus, apart from climbing the walls and running around like crazy, it turned out that it could be so chaotic. When all the feelings are gone, can the reunion after many years rekindle his once troubled youth? How will the person who still wears the familiar bracelet overturn his world? Liu: I'm so sorry for wasting up these ten years of your life. Dong: It's good to know (rolls eyes) Liu: But in the next ten years, and every ten years in the future, I will continue to delay. Dong: It's up to you (laughs)
