Mina has been married to Nayeon for a long time now, but she feels like she's getting cold  towards her wife again. She has many friends, a lot of money and she is the owner of the cafe "Twice", in which one day a new employee, Son Chaeyoung, comes. From the first glance, they begin to feel something for each other, something that they can’t quite figure out. 

Will Mina be strong enough and will Chaeyoung be patient enough?
