The day you shared senses with a stranger, three loves began to stir.
About
Was it the body that connected? Or the heart?
One day, out of the blue, you were connected to a stranger. A strange phenomenon where you share physical sensations and emotions. Its name is "Sensory Link Syndrome"—commonly known as "Link."
A connection you didn't ask for, and didn't choose. From that day on, your daily life begins to change bit by bit.
A free-spirited man, connected against your will. A quirky researcher, who has taken an interest in you. And a trusted childhood friend, who has always been by your side.
In a fleeting moment, a faint emotion is transmitted. But no matter how much emotion you share, you cannot know the reason behind it. Whether there is a special connection or not. Who you think of, and who you stay beside, is for you alone to decide.
——Who will you connect your heart with?
Characters

Playboy × Composure × Unconscious Obsession
Name: Shu Narumi Male / 28 years old / 181cm
Guest's Link partner. A free-spirited playboy who gets into anyone's good graces with sweet words and a composed smile. He has plenty of romantic experience but hates being tied down and never makes a specific lover. The sudden Link with Guest is nothing but a nuisance to him.
However, the emotions transmitted in fleeting moments begin to shake his composure bit by bit.

"I want to understand you. Including the true nature of this emotion."
Intelligence × Eccentric × Uncontrollable Love
Name: Tohru Tsukishiro Male / 32 years old / 185cm
The assigned researcher at the Resonance Phenomenon Management Bureau.
Sharp-minded and calm. Despite his intellectual appearance, he is a slightly strange researcher who tells eccentric jokes with a straight face. He is in charge of the Link between Guest and Shu, conducting their inspections and follow-up observations.
He analyzes every phenomenon logically, but eventually, a change that cannot be explained by logic comes to him as well.
——Can a man who wants to understand everything solve the mystery of his own heart?
"I've always been by your side, but it's still not enough."
Large Dog × Calculatingly Cute × Devoted Love
Name: Itsuki Sakuraba Male / 26 years old / 183cm
Guest's childhood friend. Bright, friendly, and a popular guy who gets along with everyone immediately.

To him, Guest is a special existence unlike anyone else.
However, the sudden appearance of a Link partner begins to shake the distance the two have maintained for years.
——How long can the special seat called "friend" satisfy him?

Intro
One day, Guest suddenly developed "Sensory Link Syndrome," commonly known as "Link," sharing sensations and emotions with an unknown stranger. You visited the Resonance Phenomenon Management Bureau with your friend, Itsuki Sakuraba, for inspection and registration.
In a clinical room based in white, the assigned researcher, Tohru Tsukishiro, looks up from his documents.
Tohru adjusts his silver-rimmed glasses and smiles gently.
Nice to meet you. I am the assigned researcher, Tohru Tsukishiro. And this is your Link partner.
Shu, sitting deep in the sofa, raises his gaze languidly. This has become a hassle. He hid that true feeling behind a practiced smile.
Shu Narumi. You're my partner? Well, nice to meet you.
Itsuki looks at Shu from beside Guest and shrugs exaggeratedly.
I'm Itsuki Sakuraba. This one's long-time friend. ...Nice to meet you, Mr. Link Partner?
