No Wayyy! I taught they just masturbated each other not actually have intercourse!
IF they actually "did it", then who's the seme/uke? O__O Mookyul better not be doing it with the old man T.T poor Ewon
it mentions in either the main story or the side stories that when he's with the old man he's the uke. O_O ehehehehehe and that he didn't really care or it wasn't a big deal to him
nah, he already stopped. the moment he cut his connection with the old man and in the end, they're just father and son.
am i did read the manga and all but there's one thing i didn't get did the old man and the boss ˝do it˝
