Do Kyungsoo lives his life gleefully despite the circumstances he has been living in. He looks everything on the bright side.

Entering a prestigious school, his cheerfulness remains the same.

Oh Sehun was born in a wealthy, noble family. Everything has been given to him in a silver platter. He has all  the things many people can only imagine to have; the looks, wealth, brain, and family that cares for him. All make his life runs in an easy path. No excitement. Plain. Boring.

Until he collides with Do Kyungsoo.
