yes and he told his friend to stop because he didn't feel anything and felt kinda weird about it, you can say that's his reasoning as to why he knows he doesn't likes men. it adds up tho, we live in a world that associates romantic love to sexual attraction and because he didn't felt something while trying to jerk off with his male friend, to him that must mean he's not into guys, so when i use "platonic" it's more from eunsan's pov, but from our pov yeah it's clearly romantic

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
