There is a rich mafia heir who grew up with his bodyguard/best friend. Unfortunately no romance between them in Me and Thee while they are the focus of the Korean drama.
both fun romcom have top-notch comedy with a beautiful romantic relationship for the main couple: fadelstyle and theepeach. just like the actors themselves, i'd say style and khun thee will make best friends if they ever happen to bump into each other one day.
Thee and Phum two of the lead characters have quite similar personalities. They are both hot-headed and treats their love interest in a cold manner at first. Also the lead actors are the same as well, Pond and Phuwin.
