Masato Kasakabe is utterly exhausted from his demanding job, where he’s constantly overworked. His only joy in life is supporting his favorite YouTubers. He begins to dream about how wonderful it would be to live with his favorite idol, fully aware that it’s impossible in reality.

However, suddenly, his three favorite female streamers become his roommates. Now that his virtual idols have taken on real bodies, a romantic story begins that transcends the boundaries of dimensions.

One of them turns out to be Amu—an ASMR streamer and a succubus with mildly psychopathic tendencies. When Masato loses his job—and with it, all motivation—Amu offers him the chance to become her slave. By serving her, the protagonist gradually regains his zest for life. Noticing her ambiguous hints, Masato decides she definitely likes him and gathers the courage to confess his feelings, but events take an unexpected turn.
