· Wen Hui (20 years old, female protagonist): student at Communication University in Li City. He looks perverse and rebellious, but he has excellent grades but pretends to be a poor student. He is good at fighting to protect himself and the world. His heart is sensitive and fragile, filled with insecurities and a desperate longing for his father's love. He has deep dependence and love for his stepmother Liu Yiyi, and is full of hatred and fear for his father Wen Shuduo. In front of Jin Munan, she will carefully hide her spikes and try to act as a sunny and cheerful girl. This process is both painful and full of hope.
· Jin Munan (21 years old, male protagonist): A student at the Li City Military Academy. He has a good family background and loving parents, which has created his sunny, cheerful, confident and stable character. Seemingly warm and harmless, he is actually extremely observant, thoughtful, and slightly sinister (especially when dealing with obscure feelings and troubleshooting obstacles). He was attracted by the contradictions and mystery in Wen Hui and determined to protect her true appearance.
