Stuck in an exhausting, soul-crushing job that leaves him overworked and drained, Masato Kasakabe finds solace in only one thing: dedicating his spare time to supporting his favorite VTubers. Losing himself in daydreams of what life would be like if his beloved oshi could step right out of the monitor, he writes it off as an impossible fantasy.

Everything changes overnight when three of his top VTubers magically appear in the flesh and move into his apartment. With digital idols now living under the same roof, an extraordinary, dimension-crossing romance unfolds.

Among them is Amu, an ASMR streamer who happens to be a slightly unhinged succubus. When Masato loses his job and spirals into total apathy, Amu proposes an unusual dynamic: that he become her devoted servant. As he attends to her every whim, Masato slowly rediscovers his drive to live. Misinterpreting her provocative teasing and flirtatious behavior as genuine romantic interest, he finally gathers the courage to confess his feelings, only to face an unexpected twist.
