As they grapple, they tumble down together, pressed close—her flushed face, soft warmth, and sweet scent awaken unexpected desire in Mitsuru. Their heated confrontation melts into intimate tension, blurring the line between resentment and longing. Miyu’s defiant glare hides vulnerability as Mitsuru’s hands linger, their bodies entwined in reluctant passion.
