Yoshio Hideki is a high school boy who is best described as "innocent" and perverted. Deep down, he is insecure about being a virgin and just wants to be a normal boy, He was born with a small stature and a gap between his teeth.
"I will not let anyone walk through my mind with their dirty feet" , said Yoshio.
He finds it difficult to live in comfort when he has to put up with his oversexed best friend Toyoko Yamada. She has short pink hair, green eyes, and how should I say... a D-Cup. As well as Yoshio's next door neighbor, classmate, and childhood friend who takes care of him from time to time since.
Ever since they were babies, Toyoko has fallen in love with Yoshio, and is constantly hanging around him. She very much wants to enter into a "relationship of sin" with him and is very forthright in her almost constant sexual suggestions and actions.
This is Toyoko's speech back in junior high...
"I don't know why people are afraid of lust. Then I can imagine that they are very afraid of me, for I have a great lust for everything. A lust for life, a lust for how the summer-heated street feels beneath my feet, a lust for the touch of another's skin on my skin...a lust for everything. I even lust after cake. Yes, I am very lusty and very scary."
The next morning, Toyoko is sleeping in Yoshio's bed in the nude. His face turns red and pushes her if the bed without questions. As they walk to school together, Toyoko hugs Yoshio close which embarrasses him due to her breasts pressing against him and the fact that others can see what is going on.
The class representative of Yoshio's class, Harumi Inukai attempts to interfere, though cannot fight Toyoko's persistence.
Harumi says to Yoshio, "You'll be smothered in fire and brimstone. Not kisses." The
Yoshio blushes, "It's not me, Inukai! It's Toyoko!"
Harumi with embarrassment, "JUST CUT IT OUT YOU TWO SINNERS!"
Harkin then slaps Yoshio, leaving him a red bruise on the right cheek.
