Don't close your eyes - Woosan

'Nothing can hurt me anymore.'
'Your right, so I will hurt him instead.' And with that, Wooyoung's dagger was against his own throat.

Wooyoung is a key member of the Black Blood Clan, along with San, Hongjoong, Seongwha, Yunho Yeosang, Mingi and Jongho. Since young they have been trained for the sole purpose of killing whoever the boss needs to be killed. They have never once failed, after all, they don't call Wooyoung the human dagger for no reason.

One day Wooyoung is instructed to carry out a solo mission, something none of them have ever done before which makes certain people become suspicious of the boss's intentions, especially Yunho who knows something about Wooyoung he dare not speak to the others.

San, on the other hand, is determined to figure him out, to dig behind the stone cold wall of the human dagger that had been so carefully constructed and break it down. Will he succeed, and what will happen to Wooyoung when the truth hunts him down.

After all, he is not the only one keeping secrets around here.
