If you're looking for an interesting, complex story, this is not the drama for you.
It's a silly story, easy to watch, it's funny and sweet, but it has no dept at all. The characters are pretty much only caricatures of the basic drama character tropes (the quirky female lead, the kind second lead, the rich mean "villain") and are very two dimensional. Most of the time, the characters' motivations are not clear, they just do things for no reason. If you leave aside the logic and common sense for a moment, it is fun to watch. I enjoyed it, even though I rolled my eyes more than once at how ridiculous some situations are.
