Hoya is the senior of Eunji, they're bestfriend. Even they were in a different class, but it didn't block their bestfriends. Yes, Hoya had a lot of girl-bestfriends, but, most of all, he close to Eunji the most. They are neighbourhood plus their parents are really close too. Eunji have being Hoya girl-bestfriend for a long time, perhas, 3 years, or above. And guess what? Hoya had a "more than best-friend" feeling towards Eunji. However, Hoya don't think that Eunji had a same feeling towards him, really?
