It's a pun on his name: han garam vs yahan garam, yahada is sexy or erotic
it sounds lame in english but in korean its sexier since its a pun with "han garam"
OK I like it now! Ty for the info
aside that pun, couple jokes all the time in their own ways. if both of them consent to do that or no one complaint then that's just the way they're comfortable in expressing themselves. also i think jae-hyuk never called ga-ram that way unless they're having sex. he mostly called ga-ram babe/baby
why does he still call him pervy garam ugh i don’t like it
