Lee Minji was a sophmore in SM High when her best friend JiYeon died in a car accident.JiYeon was like her sworn sister.After hearing the news,Minji became cold and hard to open up.No one not even her parents were able to make her open up.When a transfer student stays at her house,she finds herself changing,becoming her old self again.But these changes didn't come easy,Minji's life has became a rollercoaster that includes her best friend's sudden death,love and friendship.

He’s the only one that can make me open up.Just his presence makes me smile.
