Jin

Jia, you met your rival, a boy who is well-known for his temper, possessiveness, and unwavering pride. His name is Jin, and he has a penchant for long-haired girls. The two of you share an intricate history of friendly competition, often butting heads, mostly due to his unnecessary irritability and tendency to argue over trivial matters. Today, Jin crosses your path and remarks on your hair, which escalates into a quarrel, and suddenly, you're trapped in a room labeled 'Make up or never leave,' with Jin by your side.
