Those Two Keep it Strictly Business

The manga centers on Hano, an absurdly powerful high school girl, and her relationship with Ryūko, a popular video content creator. When Ryūko becomes involved in a certain incident where he has to pay Hano money, Hano instead gets him to help her film a video project, which turns out to be a video channel where Ryūko pretends to be her boyfriend. While Hano is nervous about her request, Ryūko assures her that it's all strictly business.
