Istg, this manhwa is turning into a psychological manipulating yaoi. But I think he'll however end up with Hwan because you can see them together in "Stranger than Friends", in some panels.... And is also because you can see Hwan in the cover and this shit happens every time in 3p yaoi; MC dating the seemingly bad guy.
Update?? Anyone??ಥ‿ಥಥ‿ಥ
