In a twist on the typical “sugar mama” setup, our protagonist—who, despite being a 27‑year‑old man, looks like a young girl—ends up attracting a VTuber-style mama through his mama-hunting escapades. Doted on as if he were her very own child, he has no interest in returning to the home that once spurned him.

Raised without the love he craved due to the stark contrast between his age, gender, and his childlike appearance, he fought hard in his job search—only to be thwarted by his girlish looks. Forced into a NEET lifestyle for five long years and eventually kicked out of his family home, he finds himself wandering the streets in the biting cold. Desperate and determined, he resolves to try his luck at mama-hunting.

Just when he thinks “any mama will do,” fate intervenes—a striking woman approaches him. Not only is she one of the hottest mama-style VTubers on the scene, but he’s also been her fan all along. A natural-born nurturer who gets a thrill out of pampering others, she’s also an incredibly high‑spec individual: she creates avatars for countless VTubers and even streams using a model of her own design. With her help, our protagonist is given a VTuber “body” of his own, earning him a coveted spot in her ever‑expanding family.

Away from the public eye, their private moments sometimes take on a decidedly twisted, perverse edge. Through these intimate exchanges, the protagonist’s heart becomes completely devoted to her—transforming him into her very own child in every sense of the word.
