In a flat within a certain apartment blockruns a Chinese sundries select shop by Amara and his childhood friend Hirochika.But sales are hopelessly low, threatening closure...Though Hirochika handled the rent payments it turns out he settled with the building owner by having sex in lieu of payment!! When Amara tries to stop him, Hirochika instead demands sex from him, saying ‘I'll cover the full amount from now on too’...!? Residents are equally risqué and eccentric:a band member who gets oral sex from Hirochika before gigs, a male manager of a Lolita shop running an adult goods mail order site, and more.
