Void Onee-chan wants attention

The boy's friend is a beautiful 32-year-old NEET. Shota-kun is a very ordinary boy, and he has a friend. She's a very beautiful older sister next door, 'Void Onee-chan'. Her true identity is a good-for-nothing NEET who doesn't work and laments her life day and night, a total alcoholic!! Shota-kun, who has been liked by such a Void Onee-chan, tries to maintain a friendly distance, but he blushes every day because of her overly open nature. At this rate, his sexual preferences might be ruined by her...!? She's an alcoholic NEET, but beautiful and too open!!! A cute, next-door neighbor comedy about someone who depends on him!!!!
