The scene I remember is the ML and FL go on a trip (I think to see a meteor shower) and the resort/hotel receptionist tells them they only have one room (he's lying and thinks he's helping the couple).  They go in the room and there's a box of condom.  The ML tries to hide it in the couch and gets the FL to go outside with him.  She does end up finding the box of condom.  Later the ML decides to get his own room and confronts the receptionist telling him he knows there are more rooms.  The hotel then has a blackout and the ML goes to the FL to make sure she's ok and they end up staying in the same room anyways.

I think the ML is one of those capable and smart guys...not sure

If anyone knows this drama, I'll be extremely grateful???

I might be wrong, but it could be The Oath of Love
