Today, as always, the nice guy, Netori Taizo, was enjoying his freedom to the fullest.

He was busy cleaning a storage room at the request of an old acquaintance when, right next to him, a man and a woman—more precisely, a human man who could use magic and a beautiful elf princess—fell down with screams.

After talking to the two, who introduced themselves as Aaron and Chloe and were dressed in unusual attire, Taizo realized they were “otherworlders” who had wandered in from another world.

Furthermore, the two were lovers who had eloped due to certain circumstances.

With his inherent kindness, Taizo decided to take care of them until they could live comfortably in this world.

…However, this wasn’t an act of pure goodwill.

After all, Taizo was a man who openly declared his hobby to be sleeping with other men’s women and who found pleasure in training women to become the lewd women he desired. Chloe, a woman of refined elegance and grace, also becomes a target of his venomous fangs.

Chloe herself seems troubled by something regarding her nightly affair with Aaron.

Furthermore, Aaron is often bedridden due to inexplicable seizures and poor health,

creating a perfect situation for Taizo to spend time alone with Chloe without any worries.

Because she is a sheltered girl, Chloe is easily manipulated and trained by Taizo.

Aaron, troubled by his body’s lack of control, feels uneasy about the subtle changes in his lover.

For these two who have come from another world, is Netori Taizo a benefactor or a messenger of destruction?

The plan of seduction and training begins, set in the height of summer in modern times.
