Han Beonman Deoyo, Hoewonnim

One day, Hae-Won, an ordinary college student, gets hit by a task and accidentally rips a stranger's shirt. To make matters worse, Hae-Won buried his face in his spacious chest! Uh? It's kinda big... Is that guy a fitness trainer?

Hae-Won, who just registered at the gym, is feeling strange, can it be connected to U-Jin?
