I Was Loved at First Sight by the Underworld's Ruler at My Recovery Retreat

Before you, quietly passing your days in a secluded recovery facility, a man suddenly appears: Kokonoe Rei, the one who rules the city's underworld. What should have been a chance collision transforms entirely through his mad, love-at-first-sight obsession. "With a body this slender... I won't let anyone else touch you. I'll carry every part of you myself." A sweet, heavy, overprotective devotion poured out by a man who should be dangerous and cold. In a white hospital room with no escape, days wrapped in bottomless indulgence begin.
