Yea I see the similarity but ... noooooooooo :'( hope its not like that!!
Now that you've said it.... gaaaahhh. It is possible though. Maybe that's why he's concerned about Hye-in and Eunhyun's relationship because he wants to take care of his sister. And by reading the description again "things are never how they appear" Σ(っ°Д °;)っ but I hope not.
im up to episode 42 so far and nope it doesnt seem like that at all, also the author said in one of her ntoes that the only reason the hair is like that is to make it less boring because all korean students are supposed to have black hair as dress code
They look alot are they siblings...? separated...? and his bro l9ok for her... same talent... ?den the girl didnt remember....? I hope not.....
