You may mostly enjoy this drama if you have ever been a hopeless romantic with the craziness level of at least 8 out of 10. It will probably make you cry a lot or feel that pain again which you may have forgotten.

I would suggest watching during a weekend or when you have enough time to binge watch the series. It gets heavier and heavier, so make sure you are prepared for it.

Avoid watching this if you were expecting a feel god romantic comedy. It mostly made me feel sad and depressed, but not all dramas can do that either; so it could still be something worth experiencing. Depends on your taste.

It could have been fewer episodes as I started loosing the emotional connect after episode 12. But if you watch 12 episodes, you may as well watch all of them.
