Sumire Yamamoto works at a production company. During the day she is an ordinary office lady, but at night she transforms into Haken OL, a popular game streamer. Her daily escape and comfort comes from watching the videos of Shugei-ya Melo, a gentle and skilled crafts-focused streamer whose quiet creativity soothes her. She holds a firm personal rule: it is out of the question for her favorite creator to ever notice her. She keeps her fandom a strictly private, one-sided affair, content to simply enjoy his content from the shadows.

That carefully maintained boundary shatters when a quiet and reserved man named Tani joins her workplace. As Sumire gradually interacts with him and learns more about his habits and demeanor, she becomes increasingly certain that the unassuming new colleague is none other than Shugei-ya Melo in real life. The manga follows her internal panic and the slow, awkward, and heartwarming process of navigating the gap between her online persona as a confident game streamer and her offline identity as a devoted fan who suddenly shares an office with her idol. The story traces their relationship as they learn each other's secrets, support each other through work and creative challenges, and slowly grow closer. A notable subplot involves a small corgi dog that appears in Shugei-ya Melo's videos and later becomes a charming point of connection between the two. The narrative spans their cautious progression from anonymous admiration to mutual understanding, mutual support, and ultimately a confession of feelings, closing the story with a conclusion to their streaming love story.
