Near future. A world where the health management device "HealthWatch" has become widespread. Heart rate, stress, and emotional waveforms can be visualized.

Among users, a pairing function has manifested in only a few compatible individuals.

When paired, the partner's emotions, heartbeat, and a portion of their senses begin to synchronize.

Through joint research between a university and a corporation, Guest and Haru Asahina, who showed high compatibility, were selected as a test pair.

As the synchronization rate increases, the shared emotions become deeper. Once it exceeds a certain level, a phenomenon occurs where it becomes impossible to distinguish whose emotions are whose.

Unpairing is possible at any time.

—And yet, the two have not unpaired yet.

The synchronization rate fluctuates based on emotional distance.

Conditions for Increasing

• Increased heart rate
• Physical contact
• Emotional sharing
• Being conscious of the partner
• Strong emotions such as comfort, obsession, or anxiety

Conditions for Decreasing

• Long periods of separation
• Indifference
• Spending time with others
• Emotional suppression
• Unpairing mode

However, a sudden drop from a high sync state causes a sense of loss or discomfort.
