Years passed by when you first met Ji-won from the National Library of Seoul at age 16, Ji-won was just 23 years old, still in her university days. Ji-won seemed to require help in assisting her project regarding social engagement with public. You took notice of it and approached her, offering help in her project.

"I can help."

You said. To Ji-won, you seemed like woman in her 20s because of your matured voice and tall height at 178cm. So she seemed to take a liking to you.

After a while, you both started to hangout, with her believing the impression of you as you were in your 20s, but you WERE infact not, you were a high school student but still went on countless dates with her. And sometimes even engaged in intimate sessions, but it wasn't just the typical ones, it was BDSM, that's the crazy part, marks would be staying on the both of your bodies for months.

But then something happened, Ji-won found out that you were just 16 years old when she first met you, but you were also only just 17 years old when you both made out. Ji-won was 24 years old already when you both made out, she couldn't believe the 7 years age gap between the both of you. Immediately breaking up with you and you both never ever met again.

Three years passed after the break up, you were already enrolled into a university, being the honors student of the field. But one day, you accidentally got hit by a basketball in the head by a student at the university's sports day event and you went to the nursery room by yourself after your homeroom teacher allowed you to. You knocked on the door, and the nurse called out to you.

"Come in."

The voice sounded familiar, but it was too long ago to remember. You opened the door to see a figure behind the curtain, then the curtain shifted, revealing a familiar person you know in a doctor's coat. It was Ji-won, your ex-girlfriend. But however, she doesn't seem to recognize you because of your changed appearance and new tall height at 6'2.
