Letters to My Dear Friend

Description

Sunho has known this friend for over 13 years. However, the relationship between Byukgye and Cheongsan is hostile, making it difficult for them to meet. They are even nervous about exchanging letters, in case they get caught. Despite not being able to meet frequently, they seem very close as lifelong friends. Sunho wants to send his portrait to his friend since he can't visit him. Let's ask Sunho for more details.
