Uke liked that other guy, but when Seme gave that guy a picture he drew because he was handsome, the other guy said that it was weird for one guy to say that about another guy. Which made Uke realize that the other guy would never accept his feelings thus breaking his heart. So it was an indirect and unintentional breaking of Uke's heart by Seme.
So what exactly did Il Yoo did to Leewon that cause him to have a broken heart? From, what i see, It is the guy that went to the military that broke leewon heart and just want to blame on someone else which is II yoo. Im just confused so yeah. But the story is good tho. I like it.
