An assertive, beautiful girl moves under the same roof, and their heart-racing cohabitation begins!
Julie suddenly shows up at the apartment where Shiroki lives. She's a sweet girl who cares about her older brother, and a beauty known throughout the school. That's all Kyu thinks of her, until she suddenly says she wants to serve as collateral for her brother's debt. And all for a mere ten thousand. “Until my brother pays you back, I'll gladly be yours, senpai!” Julie declares, looking inexplicably happy. It all happens so suddenly that Kyu is baffled, but Julie persuades him to let her move in and starts preparing to live at his place. Of course, there's more to Julie offering herself as collateral for her brother's debt than meets the eye...
