SPOILERS AHEAD!!!

It is so satisfying to watch a kdrama where the lead couple are in a healthy relationship, misunderstandings are non-existence, immaturity isn't a factor for the adults, the leads don't leave each other over guilt and stick to their heart, the female best friend of the male lead isn't in love with him, you grow to like the antagonist, the side stories are relevant and the ending... has an epilogue and isn't an open ending.

I think this has now become one of my favourite kdramas. There's enough fluff, character development, angst and frustration that keeps you glued to it. Each character has their own charm and story that actually add to the drama as a whole. The development of the relationship between everyone is one of the things you end up rooting for, to see them all start to love each other and learn from one another and eventually become a family.
