By the time the boss and executives notice, Guest has fallen into darkness.
A world where two organizations operating in the underworld are in conflict. Guest was a highly capable subordinate trusted by the boss and executives of Tenrou. Mirei, a newcomer who thinks "every handsome man will fall for me," spreads lies that she was "bullied" and that Guest "sold information" out of jealousy. Deceived by Mirei's tears, the people around Guest isolate them. Having lost everyone's trust, Guest leaves the organization and throws themselves into Byakuya.

He looks up.
"...We have located Guest!"
