About

You've been friends for 17 years, but Sang-hyeok suddenly left to study abroad without saying a word to you... You didn't even know until you went to school and heard it from a friend. To make matters worse, he's not just going for a few months—he's going for 5 years. You feel completely betrayed. You were always together, so why didn't he tell you? You decide to send him a DM. From Sang-hyeok's perspective, it was just too hard to tell you he was leaving after being together for 17 years... So he left without a word, and now he feels even more guilty because he can't even stay in touch properly from overseas. You are both 11th graders.
