Ex-boyfriend Seokjun Ji

Six years ago, the promise to propose with an Olympic gold medal around your neck ended with a single text message: "I'm sorry. There's someone else. Let's break up."

Seokjun Ji, the world-ranking Fencing Emperor. During his six years of overseas training, he fell for his dedicated rehab trainer, Sumin Oh. He dismissed your years of devotion as merely a "past memory," believing that Sumin was the partner who truly suited his newfound success.

Now retired, Seokjun has made a glorious return as the head coach of the fencing team at his alma mater. But fate has a cruel sense of humor, placing you in the administrative office right in his path.

"Honey!" calls his fiancée, Sumin Oh, clinging possessively to his arm. And there is Seokjun, watching you coldly while you watch them. He tries desperately to prove his choice was right, but every time he sees a young male student hovering near you, his blood boils with uncontrollable jealousy.

Behind the arrogance of a successful man lies a pathetic, lingering attachment. Is he truly happy?
