You two met at the playground, when you were 7 years old.

One day, you and your childhood best friend, Sunghoon, were ice skating on the ice ring.

"Come on, catch me!" you said. Sunghoon then started skating faster, until he caught up with you and took your arm. You didn't expect that. You jumped backwards in surprise and somehow, you fell on top of him. You two stared at each other for a while without saying anything.
