Jiang Yinuan's hairpin was snatched away by Bai Haochen, so she took away Bai Haochen's coat
"Jiang Yinuan, give me back your coat!!!"
"I won't, Lianluanluo. Unless you return my hairpin to me first."
"Forget it then"
Jiang Yinuan looked at Bai Haochen's frozen appearance and lent him her school uniform. This incident started their love journey.
Concept: The love between the male and female protagonists is not recognized by others, but it becomes a love that others envy, from campus to wedding dress.
