It's a very normal story about two people who share pain and disappointment about their life and the unexpected path it took.

After long years of hard work to be a doctor Ha Neul (Park Shin Hye) requit her job after knowing that she is depressed to take a break to think and take care of herself. In the other hand we have Yeo Jeong Woo (Park Hyung Sik) who is a very popular Plastic surgeon, but loses everything after a terrible surgery. So he moves on the roof in the house of Neul.
Then we got to know that were classmates in the high school, not a normal classmates but a very competitive ones, so we got to see many and many funny moments between them and also flashbacks when they were just students and believe me they competit about everything like : "let's find out who has the worst life !?" Hehe .

And i loved how they support each other when they're at their worst, and how she believed he was innocent from the first moment.
i loved the chemistry between Shin Hye & Hyung Sik ( something i wanted to watch since the Heirs).
And how warm and cozy is the dialogue in the drama! I cried in many scenes with them ㅠㅠ
I loved many supporting characters too like Nam Ba Da ( God, the sister brother interactions are so natural and funny),
And i liked Dae Young ( a true friend trusts in you even when everyone claims you are guilty).
I never wrote a review before watching the whole drama BUT this one is special!!! Can't wait to see more :)
