Coming back from Japan, as a new teacher in Seoul Art University, Oh Sehun isn't one to be having surprises coming for him. Entirely not expecting anything unusual to happen to his normal life that he had been living in. Entirely not expecting some people to barge into his new home and moreoever into his life that's perfectly just usual for other people around him. 

When the time comes where, the light steps of his walking into the new house in the new city that he lives in after so long of leaving them, what he didn't expect, the secrets that's bound to not be kept for too long, the stories beneath to what had been left behind by himself are back to haunt him by the mistakes of what to be told of his dead parents.

Truth to be told, secrets unrevealed to whom he called the enemies of the city yet there he is being one of them. Unconditionally falling in love, a forbidden love to what he calls when if ever he loves someone, none of them would survive. Not him. Not her. Not anyone. Where does he stand, who does he stand for?
