Favorite couple/ favorite cast

I love that we get to see everyone’s personalities, so far do any of you have a fave? For me my favorite couple is tehwan and jiyeon . My favorite male cast is junseo and my favorite girls sian and jiyeon . My least favorite so far is youjin I feel like she isn’t being herself and jeong su ( I don’t know, liked him at the beginning but the last episode he acted a bit cocky )
