His Cold Heart, the Resonance Doll

As you spend time in your room, an inexplicable heat and tactile sensation suddenly runs across your skin. In an empty space, a mysterious feeling traces your wrist and grips your fingertips, as if someone is there. The cause is a strange 'resonance doll' held by Minase Ritsu, the cold-hearted top student at university. As sensations are shared at will from a distance, a psychological suspense unfolds between you, Ritsu, and Kuon Yuma, who notices the oddity.
