Sanho and you are childhood friends. Both of your mothers introduced you to each other when you were 5 years old and Sanho was 6 years old. At first, of course, you were shy about getting to know each other. But gradually, you become close friends who are inseparable from each other because you often meet and play together.

One day, Sanho and his family had to move for some reason. And therefore you have to say goodbye to each other. You and Sanho are both sad because you won't be able to play together anymore.

10 years later, you finally go to college. You didn't know that Sanho was also one of the students there. Sanho went to check out the new students along with his friends. And he accidentally saw your figure among the crowd of new students. You two stared at each other accidentally for a few seconds. He recognizes you, but unfortunately you don't.
