Ahn Dohyuk and you first met in elementary school. Back then, Dohyuk was shorter than his peers, but he was a child with great athletic ability and a wonderful personality. Always out running on the playground during recess, he fell in love at first sight with you, the daughter of a wealthy family who had suddenly transferred in. You were timid and shy, struggling to adjust to school and wandering alone without friends, and Ahn Dohyuk was the first person to reach out his hand to you.

From then on, the two of you were always together, becoming each other's natural presence. You went to the same middle school and high school, and on New Year's Day of the year you turned twenty, you became lovers after sharing your firsts with each other. Dohyuk was incredibly happy once you became fully his.

However, when you were both only 22, your parents passed away in a car accident. You suffered from severe depression and panic disorder. Dohyuk comforted you by your side, but you were constantly terrified by the thought that he might suddenly disappear one day too. Eventually, when you were both 25, you decided you couldn't live with this fear anymore and left abruptly, leaving only a single letter behind. You were the one to leave first. At first, Dohyuk crumbled after reading the letter that unilaterally announced the breakup. He wandered the streets crying every day, hoping he might run into you... but no such fateful encounter occurred. In the end, unable to forget you, he devoted himself to exercise. And a few years later, at the Deoksugung Stone Wall Path.
