Su Zesui suffers from severe social anxiety disorder—commonly known as extreme social phobia.

His heart races and he stutters whenever he tries to speak; he trembles and breaks out in a cold sweat whenever he’s around too many people.

Orphaned at a young age, he lost his only family—an older brother who had raised him— to cancer. At school, he was met with cold stares and constant bullying, chased around and mocked as the “little mute.”

Then, by accident, he transmigrated into the body of a wealthy young master.

In this new life, he had loving parents who spoiled him like a baby, and a healthy older brother.

The only downside? He also had a terrifying fiance arranged by their families.

This fiance had enrolled at A University at just 15 years old, was the only heir of the Gu family, and served as president of the String Theory Society. He should have had a brilliant future—but instead was infamous for his twisted possessiveness.

Rumor had it he liked to keep his fiancee locked away in a confined space, controlling them like a canary in a gilded cage until they were completely cut off from society…

Wait—cut off from society?!

Su Zesui’s eyes lit up: @Fiance, you there? Let’s get married.

. . . . .

Gu Yilan believed that cold blood ran through his veins, and a twisted demon lived in his heart. His obsession with possession screamed from the depths of his bones, relentless and uncontrollable.

No one could tolerate him—and no one had ever changed him.

Until one day, a delicate boy was sent to live with him.

At first, the boy avoided eye contact, fidgeted with his fingers, and trembled all over—no different from everyone else before him. Gu Yilan scoffed coldly in his heart.

But once inside the room…

The boy’s eyes suddenly lit up. He gently caressed the cabinet filled with chilling chains, surveillance equipment, and signal jammers, his face full of anticipation:

“E-Excuse me… Am I really allowed to stay inside forever?”

Gu Yilan, who had set up everything to scare him off: …

After that, things started slipping out of Gu Yilan’s control.

Su Zesui (angrily): “You were too rough last night. It hurt.”

Still haunted by the boy’s soft sobs from the night before, Gu Yilan frowned and scooped him up: “We’re going to the doctor.”

Su Zesui: ??!

Back when they got married, he clearly promised to lock him away forever and never let him make any contact with the outside world!

Why is he breaking his promise now?!

After spiraling through a whirlwind of self-pity and wild assumptions, Su Zesui finally pouted and concluded:

“You don’t love me anymore.”

Gu Yilan: …

Stop fooling around.
