第1章 千早家的赘婿只想过平静的生活 

The son-in-law of the Chihaya family just wants to live a peaceful life

Transported into a yandere dating sim, he becomes an irresistibly charming pretty boy—only to face a bad ending involving a kitchen knife.
All Itou Seiyuu wants is to stay alive.

To survive, he chooses to marry into a powerful conglomerate by getting engaged to the heiress Chihaya Airi.
Airi, who naturally despises men, was originally a non-romanceable character. Their engagement was merely for fulfilling her family obligations, while Seiyuu planned to use this status to shield himself from the obsessive yanderes around him.

But instead, Airi’s close friends begin to desire Seiyuu more and more.

“I’m already engaged. Please show some restraint.”
“Isn’t that even better?!”

Each of them has their own unique skills—and their secret weapons will blow your mind:
Mind control, time freeze, telekinesis, dream invasion, thought theft, reality-bending domains…

Seiyuu's peaceful life is shattered. Surrounded by dangerous women who are all after him, he’s on the verge of mental collapse.

To make matters worse, Airi’s gaze toward him starts to change.
What was once cold disgust is slowly turning into obsessive, possessive love.
