I lovely love both of them. I cant pick one?.
They're good looking and give us bright-warm aura right? Unfortunately, moment development is too sudden. Too short! I can say that the Bus station scene is the killing moment. When they're drunk and touched lip. Omg. I apreciate the main lead is NOT a sus-tsundere (act like coolest and being selfish) its great!! Its warm couple. Their style is Fit and simple.

Bong dok.. that was a pitty. So sorry..
Yeah again. Its too simple and short. We can imagine many possibilities to happen in the boarding house. More funny and not a stuck momonet like Hae Soo and his sunbaek (novelist couple) they're potential too, tbh
