To start of, the drama was almost miss out by me with a few almost the same story line drama coming around the same time. But this is the one that really stands up.
All was really very very good less the OST which doesnt worth 10 but really wanted to give a perfect score for this drama.
My personal feel why this stands up of the rest was:
1. Many small little created the smile and laughter to viewer.
2. Enjoying with relaxing but not at any point felt boring or wanted to skip or fast forward even already knowing whats going to happen next.
3. Created a loving and hopeful mindset for viewers
