Nagisa Kataoka and Sakura Tsukishima are senior and junior at the same company. Due to the impact of COVID-19, the company has begun to encourage teleworking. Sakura, who liked working with Nagisa, decided to work at Nagisa's house, using the excuse that "I can't get any work done unless my senior is watching me."Sakura had a plan that went beyond the relationship between senior and junior. That was to have a physical relationship with her senior, Nagisa.
