I'm giving this drama a high rating because in my opinion it deserves. Why ? Considering the plot and the genre of the drama, the director, writer and everyone else worked really hard to make this drama not even for a second boring. It was so easy to watch this drama as it didn't have dark,stressing or dull moments. Perfectly made for those people who likes to watch simple romantic dramas. It isn't my favorite genre, but i was in the mood for a simple romance drama that is mainly a pass of time. The story is a very simple one, not complicated. Contract relationship & contract marriage, which we are used to seeing in kdrama world. but the unique thing about this drama is that the couples progressed greatly and perfectly, and there were many good loving moments in their relationship than arguing and bullying (which is really something rare in kdramas). The couples were extremely cute together and their chemistry is no joke to the extent that it would actually convince me that they are real couples and not just on screen. Overall it was really fun watching this drama, worth my time.
