I don't think that this was a little boring because of the main leads. I have seen other dramas from them and they did their job perfectly, but the plot was a lot more interesting. There were some big misunderstandings between characters that were resolved almost at the end, which I didn't like at all. I liked female lead's character and male lead's character, but the romance between them almost didn't exist. Male leads friend who was a girl, was very manipulative towards him. I think if her character didn't exist, the drama would be much better. The main couple had some cute scenes. I don't think this is the worst thing I have ever seen, but I don't think it is remarkable either.
