A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

It was supposed to be her sister's wedding night, but she was schemed by her biological mother, drugged, and sent into her 'soon-to-be brother-in-law's' wedding car.When they first met, the man in the wheelchair was as dignified and cold as rumored. Just because she approached him slightly, he grabbed her neck, nearly choking her to death.'A woman marrying into the Fu family must rely on herself to survive, understand?'She nodded frantically, thinking that carefully pleasing him would allow them to live respectfully and peacefully like guests for a lifetime.Yet in the nights and days of accompanying him, she was thoroughly consumed, step by step falling into the trap he had long set.In this life, there is no escape; in this love, it moves the heart.
