A female college student lives on the upper floor of an apartment building. Even so, she is called a plainly dressed otaku girl. I wasn't really interested in it, but the manga made me go back and forth between each other's rooms. It's miraculous that such an old man would befriend a girl who is much older than him, but the surprise doesn't stop there! The sober virgin's true identity is that she's curious about male genitals and often masturbates, plus she has big breasts like in a manga! The days when they devoured each other's bodies like crazy.
