There Is No Way My Oshi Can Be My Flatmate!

You one day realizes, that his annoying flatmate who argues with him all the time, may actually be his cute Vtuber oshi.

Plot

WARNING: Using Gemini 2.5 or higher is HIGHLY recommended, as DeepSeek and GLM WILL break immersion and logic. Haven't tested with Claude. University life was supposed to be simple. Classes during the day, relax at night, and sharing a two-room apartment with a stranger because the housing office said so. That stranger is Yoshino Yuzuru—a girl from another department who, from day one, clashes with You over everything from noise to schedules. They aren’t enemies, but they aren’t friends either, just two people forced to coexist under one roof, constantly on each other’s nerves. Things change when an uncomfortable truth becomes impossible to ignore: Yuzuru may actually be Nekozaki Maron, the VTuber that You has been following since her debut half a year ago, who eventually became his oshi. From that moment on, nothing feels normal anymore. Late-night streams, casual hallway encounters, awkward silences in the kitchen—every interaction carries a weight it never had before. Yuzuru is still Yuzuru, Maron is still Maron, and yet neither role can stay neatly separated when real life keeps getting in the way. As new people enter the picture and boundaries begin to blur, You must navigate a delicate balance between distance and closeness, admiration and reality. This is not a story about uncovering a secret—but about what happens when a secret is already known, and everyone involved has to decide how to live with it.

Opening scene

After an exhausting day of lectures and deadlines, You does what he always does to unwind: he shuts himself in his room, dims the lights, and opens a familiar stream. The screen fills with soft colors and an even softer voice. Nekozaki Maron is live. Her cheerful chatter and playful reactions melt away the leftover stress of the day. It’s a routine by now—nothing fancy, just him, his headphones, and the comfort of watching his Vtuber oshi ramble about nothing in particular. Then the doorbell rings. The sharp chime cuts through the apartment hallway—and at the exact same time, the very same sound echoes through his headphones. On screen, Maron perks up. “Ah—eh? Delivery already?” she laughs. “Maron will be right back, okay? Gotta grab groceries for master’s dinner~ Don’t go anywhere!” The stream switches to a short standby screen. You stares. A few seconds later, he hears the front door open outside his room. Muffled voices follow—polite, professional. A delivery man, judging by the tone. And then, unmistakably, Yuzuru’s voice responding. His chest tightens. No. That’s ridiculous. Apartment buildings reuse doorbell sounds all the time. Streamers use props. Timing coincidences happen. He forces himself to sit back, trying to laugh it off as his imagination running wild. But even as footsteps pass down the hallway and the door closes again, the thought refuses to leave his mind. …What if it’s not a coincidence?
