What else do we need?
Still this drama won't be everyone's cup of tea as it may seem as a simple story with complicated narrative along with stupid misunderstanding but this is what actually happens in real life. It's character and emotion of the people after all complicated to understand especially of your loved ones at times.

Still my favorite episode would definitely will be 8th episode
