He didn't know that he would see Mieum ever again. The last time he saw Mieum was, when he got hit on the head, so I guess Jitae might have thought that Mieum died.
And it's not like they were a couple, they were kids, and hasn't met for so many years.
Jitae is free to do whatever he wants
He is sure free to do whatever he wants but my point is.. if you like someone, u can't do that to anyone and u will wait for him or even that person is already dead, that doesn't just apply to couples. If he only only did it with one person, I think it's acceptable, but It's the opposite. ╮(￣▽￣)╭
I don't really understand if the top was actually like the bottom since before or he's just interested to him now because.. WHY WOULD YOU FVCK MANY/OTHER PEOPLE IF YOU LIKE SOMEONE ┑(￣Д ￣)┍
