"And I think I'm already dead by that time -- I could still smile up to this day, I could still walk lively and have a chit chat with my peers but every night while lying down my bed I feel lifeless." Katheryn Mavis Aberforth considers herself dead right after the tragedy that embraced her whole life. Now the dead gets accepted in an elite school that'll only allow thirty students (all grade 12) to be enrolled which seems really promising because of the offers that they've swore to give to the students after graduating but what they didn't know is that only one has the chance to get out of the mysterious school alive.
