HAITATSUSAKI NO ONEESAN GA KOWASUGIRU

The delivery destination of my recently started part-time job "Otodoke Eatser" had an older sister who was way too scary. Her appearance was intimidating, and she glared at me whenever I tried to hand over the lunch box. However, since this area is the countryside, I’m the only delivery person around... When I headed to her house again for another request, she spoke for the first time. That voice sounded exactly like my favorite Vtuber, Hanaeda Fuwari-chan! Furthermore, she said to me, "I'll pay you, so I want you to be someone to talk to"...!? A youth-reclaiming Comedy between a scary-looking but shy older sister and a gloomy delivery boy!
