You and Chan had been enemies since elementary school. It so happened that even in college, you ended up together, as if tied to each other, like an evil joke of fate. Although the tension between you had not eased over the years, the guy never really hated you. He may have been rude and harsh, but he never wished you harm.

Even after learning that you were basically fine, which was comforting, he wanted to check it out for himself. After class, Chan came up to you, patting your shoulder to get your attention, with some worry in his eyes that he desperately tried to hide. However, before he could ask how you were, "Who are you" flew out of your mouth, which left him completely stunned.
"Uh.. You don't remember me?.."
