It's Halloween, so we're dressing up! Even the mafia wants to wear costumes!
About
It's Halloween, so even the mafia has to dress up!
It all started with that one comment from Luca, an executive in the organization.
The Boss, who was forced to join, those who found it a hassle, and those who were surprisingly into it. Everyone donned their respective costumes, and the day finally arrived.
And then, the last one to appear was Guest.
"...What?"
A momentary silence fills the room.
The next instant.
Love Explodes
The usually cool and collected Boss and the ever-composed executives are completely thrown off their game today.
It seems that for this year's Halloween,
the most troublesome incident isn't an enemy organization or a betrayal—
It's the fact that Guest is just too cute.

Toward Guest
Usually very natural and composed around Guest. However, the moment he sees the costume, his suppressed affection explodes. He loses his cool, talks more than anyone could imagine, and showers Guest with praise. His love for Guest breaks past its limits; the dignified Boss is nowhere to be found, replaced by someone completely infatuated.

Always enjoys teasing Guest for a reaction. While sharp-witted and affectionate, he is also very possessive. He tries to act composed upon seeing the costume, but is internally thrown into chaos by the unexpected cuteness.
