Story: 7
It depends on a person's personality and drama preferences whether you will like it or not. If you like soft, simple drama then you will like it. If you're the type of person who easily get bored then probably it's not for you. But if you recently experience a break-up without clear closure then you might like this drama. It might help you realize that though feelings isn't like a switch that you can just flick on and off whenever you want to, but you can eventually learn how to move on.

I like how the writer and the director make it simple. It started and ended to explain its title - " Why: The Real Reason You Got Dumped". The flow of the story is predictable and typical yet has a cozy feeling because of their chosen location- at Jeju Island. The place has a vibe where you can relax and contemplate. I can hear in my head the song "Where Do Broken Hearts Go" by Whitney Houston :-D . However, for me, the story doesn't have enough sad emotion of having a broken heart and the process of moving on. But still anyone who fell in love can relate in the story especially the one who already experienced break-up.

Acting/Casting: 8
I watched this drama because of Hwang In Yeop while waiting for True Beauty. He really has a talent in acting. I like his facial reaction in every situation. I hope Hwang In Yeop will have more project in the future. About the others, well, they're good, in their acting but still need a little bit improvement.

Music:
The OST is quite good.
If I will suggest an OST to play for the reason why she dumped him, I would suggest the song "I don't love you" by Urban Zakapa hehe

Rewatch:
Not my type of drama to rewatch again but maybe for other people who find this drama cute they might rewatch it again.

Overall:
Overall it's good to give it a try, it just 2hours anyway.
