Looking for a drama : Romance without triangle

Hi everybody ! I'm looking for a Drama ( japanese, korean, taiwanese etc ) who mix Romance and something else ! For exemple , City Hunter mix a romance with a lot of action ( I don't want such action ! ) , Queen In Hyun's Man mix Romance ( yes a lot ) and "others problem".. I don't love Triangle Romance , I mean It could be okays in some drama but I prefer when I see only one couple ! So I hope some people will help me to find some news drama (The drama could me old also)... But I want a real romance not only some few moments ... And if it can avoid policy and mystery I'l bee happy ! I hope I don't ask too much Thank U , and please if you have a idea tell me ! ( Could have a triangle but not a strong , .. in the best case, any triangle at all ) SOrry for the English mistakes ( but I hope more people will answer me )

I think Nagareboshi does not have a triangle.
