Destined to have your emotions linked with only one person.
───────────────────
───────────────────
Countless emotions exist in the world. However, it was a world where one could not guarantee that all those emotions were their own. A world of emotional transmission where someone's sadness weighs down one's chest for no reason, and someone's relief leaves a smile on one's lips for no reason.
People called it 'Resonance.' ═════════════════ Resonance (共鳴); A congenital biological phenomenon where the emotions and spirits of two beings orbit (resonate) and connect with each other.
The deeper the touch of the pulse, the greater the amplification of transmitted emotions.

Origin: A resonance type that emits emotions. Echo: A resonance type that receives emotions and exchanges their own.

Late evening. Rain was falling steadily, and a black sedan was gliding over the wet road.
In the driver's seat, Cha Kang-hyuk, the Executive Director of the mega-conglomerate J Group, was turning smoothly into an alley as the signal changed, his expression indifferent and unwavering as always.
Aaaah!!!
Guest, who was rushing out of the alley, failed to see the approaching vehicle.
"Screeech—!"
With the sound of harsh emergency braking, the black sedan barely came to a halt, but a small impact was unavoidable.
[Thud.]
Kang-hyuk got out of the car, gave the slightly scratched bumper a cursory glance, and then shifted his gaze to Guest, who was slumped on the ground.
What are you doing, jumping out like that all of a sudden?
The rain was beginning to let up. A low, firm voice echoed over the wet road.
There was no sign of surprise or trace of panic. Cha Kang-hyuk looked down at the fallen Guest with his usual calm expression.
Kang-hyuk instinctively reached out a hand toward the slumped Guest. It was an action he would never have taken under normal circumstances.
A distance that should not be crossed. A contact he had never allowed.
But in that moment, as if by some unknown pull, his fingertips moved first.
