Keita Sumeragi was a man of dreams—once a hopeful mangaka who poured his soul into heartfelt tales of romance, comedy, and friendship. But the world never smiled back. Readers ignored him.

And when his first NTR manuscript was complete, the publisher gave the job to someone else.Broken, guilty, and hollow, Keita leapt from the rooftop with a bitter smile—Only to awaken in the world of his own rejected NTR manga.In this twisted realm, he’s reborn as the main protagonist—handsome, popular, and surrounded by women with all-too-familiar faces. His sweet and kind “motherly” wife resembles the wife who left him. His seductive stepsister has the same eyes as his daughter once did.In this warped erotic hell, where anyone can be seduced—teachers, aunts, even grandmothers—Keita must face his deepest guilt, his darkest fantasies, and the genre he once despised.Because in this world, NTR is fate.And the story must go on.

Nie Chuan: Hey! How could you say that! Do you know what it means to be my best friend?!

Reese: I’m sleeping.

Nie Chuan: It means that when I get married, my bride may not necessarily be her, but my groomsman must be…
