Siwu doesn’t do relationships — just low-maintenance hookups with no strings attached. So when Huiwon, a younger classmate with no apparent sex drive, a great body, and a frustratingly handsome face, starts hanging around, Siwu figures he’s found the perfect arrangement.

“Hyung, you’re more good-looking in my eyes... You're so handsome…”

But Huiwon barrels in without hesitation, and the emotional walls Siwu built so carefully don’t stand a chance.
As Huiwon keeps crossing lines and closing distance, Siwu keeps telling himself the same thing:
"It'll be like taking care of a stray dog... I'll just offer him foster care until someone better comes along."
