Lee Kyungri is just a normal girl who lives her life alone in Canada as her parents are always out for business trip.

One fine day, they came home and told her that she would be moving to Korea as they think it's not safe for a girl to live alone in the apartment.

She'll be staying at her parent's best friends' house for the time being until they settle all their business and move to Korea together. She was totally going for it but once she found out that she will be staying with her former neighbor under the same roof does not pleased her.

She remembers all the negative sides of him. He's cold, annoying, irritating, bossy and a complete jerk.

He's no other than... Kim Seok Jin.

Kyungri left without a single word with her family to Canada.

Not even a goodbye to him. Did she realize how hurt he was?

Guess not.

But as time pass…

Will Kyungri fall for him?

Or…

Will he fall for her instead?
