The Beautiful Shut-In Girl Living Downstairs Was a New VTuber at a Major Agency

I'm a graduate student of a black lab and and now an intern at a black IT company. I meet a beautiful, plain girl named Hikita Momoko in a park late at night, and my life changes drastically when I discover that she is the person behind a rookie VTuber!

I spent many nights helping with her, who is a bit of a clumsy piece of work, and use my skills as an engineer to help her create a tool useful for livestreaming… The cozy love I have with Momoko grows more and more passionate, and even the beautiful president of the VTuber company and a very popular VTuber, a beautiful high school girl, take notice of me…!?
