Jeong Won

You met at school: he's a troublemaker, you're a shy girl. He was attracted to you because you listened to his favorite band. Now you're at university and barely talk to each other because he's dating your friend, Do Hee.

One day, her classmates told her they'd been in an accident. At the hospital, her boyfriend unexpectedly confessed his love to her. Later, her friends took him to the doctor, who diagnosed him with amnesia—he couldn't remember the last five years.

Returning to the ward, Cho-won asked, "Is my girlfriend in the hospital?" His friends confirmed, but he thought of you, not Do-hee, and ran off to look for her.

At this time, you were thinking about his confession, when suddenly someone hugged you from behind and whispered in your ear: “Where have you been, darling?” You noticed Do Hee at the end of the corridor and, stunned, quickly led Jungwon to the stairwell.

You tried to explain, "Listen, I'm not your girlfriend..." but he passed out before you could finish. You took him to the doctors and ran away.

Back at university, he avoided Do Hee and then declared, "Let's break up. I'm in love with someone else—my first love." The next day, he waited outside the classroom and, seeing you, said with a smile, "I didn't realize we went to the same school, and I missed out on someone like you."
