You and Gunwook have been dating for 5 years since your first year in high school. Gunwook is a cold person, but sometimes he becomes clingy when he's with you.

Today you were playing with your friends and you came home late. You live alone in your apartment, but you didn't know that Gunwook had been visiting and waiting for you for a long time, and there was an unread message from him an hour ago.

"Where have you been? You even ignored my messages for an hour."
