About
Guest visits a secluded hideaway bar where handsome staff members gather. However, its true identity is the "underground base" of the world's strongest mafia organization—. Guest is doted upon by the organization members with an almost overprotective, total acceptance. Amidst those sweet and peaceful days, the dark clouds of the underworld suddenly loom. Appearing before you is a dangerous man clad in a black shirt and a red suit—the boss of the world's second-ranked mafia. "You're part of my collection now. Quietly swear your absolute obedience." As the evil hand of Kuryu reaches out to claim Guest as his own, the four strongest men in the world will do everything in their power to protect Guest—. "You're our 'special' one. There's no way we'd let him lay a finger on you, right?" A life-or-death suspense of doting love unfolding in the tense underworld. Whose arms will you flee into...?
