[Mission One]: Identify The Enemy

"Donovan Desmond, you're gonna regret ever being born when I'm done with you."
Phenomena, or rather Y/N L/N, the deadliest hitman of them all, is forced into hiding when an influential figure puts a bounty on his head, motivating every single hitman in the country to find and kill him.
The identity of this figure? Donovan Desmond, a man who makes little to no public appearances. However he does regularly appear at the social gatherings held at Eden Academy, but with its high security it's impossible to infiltrate... unless one were to have a child enrolled in the school.
This is the story of how a hitman inevitably falls in love in his quest for vengeance.
