Serim’s Golden Rule Manhwa Summary

Serim’s Golden Rule is a school romance manhwa about two students who are complete opposites. The story follows Han Serim, a girl who is feared by almost everyone at school. There are rumors that she is connected to gangsters, so most students prefer to stay away from her. Serim also does not seem interested in making friends or following the usual rules of school life. She lives as if there is no tomorrow and does whatever she wants.

Then there is Kang Seungwoo, who is almost the exact opposite of Serim. He is a model student and the kind of person everyone admires. He is smart, responsible, and extremely organized. Seungwoo has carefully planned his life and always tries to do everything perfectly.

Things become interesting when Seungwoo and Serim are paired together for a mentor-mentee program at school. Seungwoo wants to complete the program perfectly, so he decides that he needs to get closer to Serim and understand her better.

However, Serim is not easy to figure out. Her strange behavior and unpredictable personality keep Seungwoo guessing. The more time they spend together, the more he begins to wonder if the rumors about her are actually true.

Their relationship slowly develops through awkward moments, misunderstandings, arguments, and unexpected chemistry. Seungwoo’s carefully planned life starts to clash with Serim’s carefree attitude.

At its heart, Serim’s Golden Rule is about two very different people getting closer and discovering that appearances can be misleading. With school life, romance, comedy, and drama, the manhwa focuses on the growing relationship between Serim and Seungwoo. The series is currently ongoing and began serialization on Naver Webtoon in July 2026. It is written by Seyoon and illustrated by Suna.

Kang Seungwoo

Kang Seungwoo is the male lead and Serim’s complete opposite. He is an excellent student who seems to have everything under control. He is polite, hardworking, and admired by people around him.

Seungwoo also has a strong perfectionist side. When he is assigned to become Serim’s mentor, he wants to do the job properly. His biggest challenge is that Serim does not behave the way he expects. The more he tries to understand her, the more curious he becomes about the person behind her reputation.

Seong Gyu

Seong Gyu is a minor antagonist in Serim’s Golden Rule who often creates trouble for Serim and Seungwoo. He tries to control Serim by offering her money and telling her to stay away from Seungwoo.
