One day, Chikako loses the key to her house and decides to move into Shinji's house, a virgin college student who lives next door to her. In a situation where a young man and woman are alone, Shinji takes a chance and attacks but fails because he can't remove his bra... Inexperience! ! She puts him in a front-hook bra and makes him practice how to treat women gently.
