Luhan, Sehun and Jongin were high school students and certainly the most bad boys of their time. Everybody knew them and were mixed between fear and admiration. They used to live freely, without thinking about consequences but when Jongin's girlfriend was killed by some other gang, there is just one word left  in their mind : revenge.

Le passé, le présent, un même jour : l'anniversaire de Sehun.
