Chen Mi Ran, the runaway girlfriend of the school’s heartthrob, endured three difficult years in high school to escape the heavy emotional burden of this "stolen love." She aspired to become a character designer and enrolled in the university’s design department, hoping for a fresh start. However, fate took a turn, and she ended up being transferred to another department. What’s even more unfortunate is that for four years, she’ll be a classmate of her first love—the boy she had foolishly left behind in the past. Zhong Wei, determined to win back his ex, resorts to all sorts of tactics to "torment her and seek revenge," in an attempt to rekindle their old love. However, Chen Mi Ran cannot bring herself to admit that it all began because Zhong Wei had mistaken her identity back then.
