Sehun was born with a rare, severe case of aplastic anemia. Even at his young, tender age of 15, Oh Sehun worries every day that he may die, leaving his clinically depressed father and toddler brother to the mercy of the cold world. He searches for anything that would help guarantee his life: medicines, religions, etc. It doesn't matter to Sehun what it is as long it would allow him to stay with his dad and brother for even a minute longer.

Luhan is the 18 year old son of major drug dealer and gang leader, Kris Wu. He spends his days dodging punches and deflecting knives, always putting his life in danger. Luhan generally doesn't have respect for any life, his or not. Then he meets Sehun. Beautiful, pitiful Sehun with his worry filled eyes and fidgeting hands. Can Luhan learn just how precious life is from Sehun? More importantly, can he save Sehun from his dark fate?
