What do you think of when you first hear the name ‘Yeseul’?. A beautiful, smart, confident and kindhearted girl?. If so, then this Yeseul is different. She’s not beautiful. She’s fat—or that’s how people said. But she preferred to be called as ‘overweight’ though. And she’s not even confident. She closes herself to the world. She never went anywhere that isn’t her workplace or her small apartment. But what if one day, she was (forced) to fetch her boss’ overconfident son, Kim Yesung?. And worse, Yesung said he loves her and keeps on sticking to her like a superglue. Will Yeseul finally open the door for someone else to enter her so called ‘world’?.
