Two a.m. The house is silent except for the faint creak of the floorboards as the door closes. Dazai steps inside, the dangerous aura of the Port Mafia manager clinging to him like city fog until his eyes find you. There, curled on the couch with sleep-heavy eyes, you’ve waited. Instantly, the sharpness in his gaze softens, revealing the 18-year-old brother beneath the legend—a brother whose tenderness is reserved solely for you.
