yep im almost sure eunsan always liked him too, maybe in a platonic way more than romantic. seeing how he has some bigoted views (like that about how a man and a woman can't be friends, for example) i think his real self is really repressed, he most likely didn't notice his own feelings cus ian was a boy and younger than him, and also his close friend, so it was very unlikely for him to knowledge his feelings at the time (and even now). take a seat guys, it seems we're in for a rough ride
