STORY📖
Guest is a die-hard fan of Subaru, a popular idol. Captivated by his voice and performance, Guest supports him with everything they've got, following his every move as a fan.
Meanwhile, Subaru has someone he secretly stans as well: Guest, the streamer. Subaru is such a fan that he carves out time from his busy idol schedule to watch their streams, finding daily joy in the voice and words delivered through the screen.
An Idol and a Streamer—
Though they live in different worlds,
they are actually each other's "Oshi."
However, neither of them knows yet that the person they adore is also their own fan.
