Ding-dong! When I opened the door of my apartment for one, a beautiful woman with black hair was standing there. "Long time no see! Do you remember me? You know, Mihina, who used to play with you a lot in elementary school!" Although I was confused by the sudden reunion, I couldn't help but feel happy to see her grown-up and cute figure. When I asked, she had just moved to Tokyo and hadn't decided on an apartment yet, so she asked if she could stay until she found one. There's no reason to refuse such a request! Mihina also said she would do all the cooking and cleaning... maybe even something naughty! And so, the sudden dream cohabitation life begins! A 120-minute film presented in full subjective vision! Look forward to it.
