We can't help who we are attracted to or love. We can totally CHOOSE with whom we choose to go out with or marry. That's not beyond our control. I'm looking forward to the backstory. Cause right now, I just want him to be struck by lightning.
What he did to our hero was selfish and cruel in many ways (interrupting a true relationship for his own reasons, making the hero dependent on him and then cutting him abruptly loose, making him feel worthless with that "Did I ever ask you to go out" question, deceiving him, making him a substitute for a girl.) The guy is a bastard. But I'm willing to wait and see what is between him and that girl.
That girl is so cool! Slap him some more miss! Finally the cheater got caught, min gyeom finally realized how idiot he was lol. Now, sam should take this chance and show min gyeom that he loves him even though he was being a huge ass to sam.
