Storywise, I think it's beautifully written. A bit convoluted with subplots in each every twist and turns, without the mess that should've been with it.

They've used flashbacks just right. It helped with the development of each of the characters. It made them human and more relatable.

The show also had a great ensemble of actors fit for their roles. I love the onscreen chemistry of the ML and the FL. It also had good OST.

Oh and the most important thing is that it had a happy ending. I'm a a sucker for happy ending.
