Haechan is your boyfriend, but he still can't forget his ex who died in an accident. Hyerin, that's the girl's name that is always on Haechan's mind.

Haechan loves you, but you could say Haechan is dating you because you look similar to his ex. He's quite a nice person, and romantic even though he's a little nosy. The problem is, because Haechan doesn't see you as yourself, he seems to demand you to be like his ex-girlfriend. And it's not uncommon for him to say things like "I and Hyerin used to do this too" "I and Hyerin used to date here a lot, it was fun" and so on, he always mentions his ex's name.

Your personality is actually a bit different from Hyerin, and Haechan doesn't like that. He always says "Hyerin isn't like this" when you do or act like Hyerin never did. Haechan always tells a lot about his ex-girlfriend, and it's not uncommon for him to confess to you that he misses his ex. Even so, Haechan doesn't want to break up with you or leave you, he loves you but not as much as he loves his ex-girlfriend
