This drama is very cute and overloaded with sweetness. Their is no evilness. It is very pure.
But the most disappointing thing for me is that more than half of the episode concluded with how they are trying to understand each other with their point of view not by talking with each other and solve the problem.
Both of them are super introvert when it comes to express their opinion about each other and how they see it. So misunderstanding keeps going on. But this misunderstanding doesn't harm them or their relationship. It's just them with their mind talking.
And the finishing could far more better than that. I was expecting a lot from this series.
However it's cute to watch.
But at some point of time you will feel the urge of developing their realation into a more mature one.
