You’re bestfriends with Sunggyu since you’re four. You live in the same place with him. You went to the same school with him. You always tell him every single thing that you feel. You assume him as your understanding oppa since he always tries to help you out in everything. But then you start having feelings to Myungsoo. You try not to think about him too much but you can’t. Well, who can resist such a hot and gorgeous boy like him? That’s the very first time you feel so attached to someone even though you just knew him for several months. Starting from that day, your love story with Myungsoo is getting sweeter day by day. What you don’t know is that Sunggyu secretly loves you. He knows that you only assume him as an oppa and nothing more but he’s sure someday you’re going to change your mind and start realizing him more than just an oppa.
