Junjae & Takuya <3   Yeong Jun & Jin Nyeo
I've only seen the first episode and a part of the 2nd one but so far my favorites are
the 3rd and the 4th couple. Although I've enjoyed seeing the other ones as well :)
709 all the way!!!!!!~
always takujae...
Room 709 those two boys r hilarious I'm on ep 2 right now I'm watching the Happy times segment and I'm dying of laughter. 
The older female and younger male one. They're funny af xD

OF course everyone likes the two gay guys lmao xD

Definitely Room 610: Choi Jin Nyeo and Jeong Yeong Jun! <3

709 takuya and joon jae <3

i watched it for the gays but tbh along the way i really started to like 609 because they had such a comfortable relationship where they both depended on each other in every way.
