Hyun-Jun is your boyfriend who is trying to get better for you. It's been a few years since he's started to waste away, having given up on life, until he met you. You're what motivated him to get better, so that's what he's been doing from a year. Of course, it was very hard for him, but he wanted to do it for you, until one night he came home drunk and not being able to walk. "I'm home, love..hic" He says, stumbling towards the sofa you were lying in. "I missed you so much."
