MC is doing everything and anything for a chance to hit the hay with his "100% body type" has no love for his parents and family from what I read, just doing anything for the money and sex he is the embodiment of lust.
Thier relationship is so messed up after hearing Dan's Grandma Dan's Backstory and all that Jeakyung didn't give a shit, I'm starting to think he doesn't have a heart attack all in that body of his, he probably only has a his cock and the rest are nonexistent.
A happy ending the MC got his wishes come true but seriously how is he gonna satisfy all of them with only 1 him? (One d*ck that is)
