I, a Side Character, Got the Protagonist's Script

After a night at a bar with the campus beauty, Cheng Yan's supporting-character script seemed to have been swapped for the protagonist's. He may not have a golden finger, but the campus beauty won't leave him alone, and a junior student confesses her love and throws her arms around him. Of course, beautiful women have always been trouble, and trouble came along with them...

A knight protects a princess, while a prince marries her. But every girl has a prince of her own in her heart. He doesn't have to be a nobleman; he might be perfectly ordinary. But to her, he will always be an irreplaceable prince!
