The Heiress Has Three Personalities, and Her Live-In Son-in-Law Loves Them All

[Transmigrated son-in-law + psychiatric hospital security guard + heroine with three personalities + golden finger: insight into mental illness]

Gu Chang'an spent ten years as a security guard at a psychiatric hospital. He'd seen more than enough “abnormal” people.

Then one day he transmigrated into the body of a live-in son-in-law. On his wedding night, he saw five words floating above his bride's head: Dissociative Identity Disorder.

Weakling was crying. Killer had a knife in hand. Smiley was laughing.

He saw through them at a glance. “Weakling, don't cry. Killer, don't rush out. Smiley, laugh a little more quietly.”

All three personalities were stunned. This man can see us?

From then on, he treated her “illness,” and she protected his “life.”

He saw through every scheme in the household, and together they turned this world that devoured people upside down.

“I'm not sick. I'm just different from you.”

“I'm not crazy either. I just understand ‘crazy’ better than you do.”

Two “patients” save each other in a grand celebration of beautiful madness.
