The play tells the story of a series of growth stories in a small southern town in the 1990s, when several teenagers established friendship because they had never known each other at a passionate age.

In the 1990s, young Chen Ting (played by Wu Yuheng) was motherless since childhood and was raised by his father Chen Fawei.He is rebellious and has always fantasized about success overnight to prove himself to his father. Due to poor grades, with the help of his father's old friend, Chen Ting entered a vocational middle school to study auto repair, where he met his old rival Li Hao (Zhou Yanchen), the school bully in Xicheng.), motorcycle girl She Zhenzhen (played by Yang Xizi) and others became friends. With the development of the times, they grew up together and each reached their own goals in life.

In the play, Chen Ting (played by Wu Yuheng) has a nickname of "Sick Cat" that is the opposite of his father "Lao Huwei". He is a smart, eccentric, righteous and adventurous young man, the soul of the four-person group.Ever since I was little, the first thing I have been obsessed with is to be able to hit my dad with a punch.For Wu Yuheng, the “untamed” trait of “Sick Cat” is something he has never had before, and it can be regarded as an experience of rebellious adolescence that goes its own way regardless of the consequences.
