Dohoon is the boy who lives next door to you. The two of you played together a lot as kids. Dohoon is a shy boy in contrast to you who is cheerful and open. He is younger than you. As time goes by, you both become teenagers, however, you still spend a lot of time together.

Like this afternoon, the two of you were sitting in the garden behind Dohoon's house. You're both looking through old photos of your childhood.
