Krystal jung is force by her mother to be an undercover employee to one of the cafe branch that they owned because some how its been loosing alot of money. To be able to do the deed she has to pretend to be a real BOY(which for sure shes totally against the idea) 

amber liu is a good looking 100% tomboy that krystal i mean kris( krystal new male name) roomate/ coworker in the cafe. 

What would happend if amber and krystal fall for each other BUT for ambers side its a BIG NO NO cause for her shes only into GIRLS!!!. 

Would amber finally gave in to kris charm and be a girlie girl for him or would she just stop her feelings. And would kris(krystal) can catch the person whove been stealing from them
