he might have his reasons, i honestly think he's too possessive also, but no one would be THIS possessive without a reason, no?
maybe because his past previous life (i heard these was sidestory of it already and in that life Hosik & him cant be together and have super sad ending)
D;
(SPOILER)
Yes, the raws indicate that Hosik had died before they could get together in their past life. That's why the seem is overprotective because he doesn't want fate to repeat itself.
@Chuoi ;__; i hate SE, that’s why i knew the raw but dont think of reading it
Seme is just too possessive for me. I like everything else but I wish he could just trust hosik
