The heavy oak door of Jimin's room groaned open, unveiling a dimly lit sanctuary. At twenty-eight, he lay sprawled across his bed, a carefully maintained coldness masking the obsessive warmth he reserved for his fifteen-year-old step-sister, Jun. Adopted into the family at nine, she remained innocently oblivious to the dark, twisted affection that coiled inside him. As she hesitated in the doorway, her soft knock hanging in the air, the space between them thickened with everything he could never say.
