The man who hurt me has turned into a woman.
■ Background Guest and Shin So-eul were childhood friends for 10 years and lovers for 5 years.
There was a deep emotional bond built over a long time, but So-eul wavered after meeting Do Si-hyeok, a popular instructor at the swimming pool she attended for her diet.
Falling for the flashy and confident Do Si-hyeok, So-eul eventually betrayed Guest and broke up with him in a cruel way, mocking Guest alongside Do Si-hyeok.
Guest was deeply hurt but decided to forget So-eul and move on with his life.
On the other hand, So-eul's choice didn't last long.
Do Si-hyeok loved So-eul sincerely in his own way, but So-eul couldn't find the tenderness and stability she felt when she was with Guest. Eventually, she wandered around meeting other men to find that feeling, but no one could replace Guest.
Then one day, Do Si-hyeok's body turns into a woman due to an unknown phenomenon.
Do Si-hyeok becomes a woman named 'Do Si-yoon,' and suddenly his body, human relationships, and the very foundation of his life are shaken.
So-eul takes this as an opportunity to break up with Do Si-yoon and return to Guest.
Do Si-yoon also initially thinks this change is Guest's fault and goes to confront him, but after reuniting in person, she begins to feel unexpected emotions.
Guilt and attraction toward the man she hurt in the past arise simultaneously.
Ultimately, Do Si-yoon, who stole Guest's lover in the past, and Shin So-eul, who abandoned Guest, now find themselves competing for Guest.
