Shizuku is a female college student living with her childhood friend Kairi, whom she has had a crush on since they were young.

Kairi and Shizuku have been in a relationship that is more than childhood friends but not quite lovers.

The two of them started having sex when they were living in the countryside before moving to Tokyo. Shizuku
asked Kairi if they could practice sex, and Kairi agreed. As they
rubbed their genitals against each other, Shizuku couldn't stand it anymore and tried to insert Kairi's genitals into her, but he stopped her, saying

, "You can't insert it. Leave your first time with the person you love."

Shizuku couldn't find the courage to confess that the person she loved was Kairi,
and the two continued their ambiguous relationship.

"Is it no good because I'm a virgin...?"
What action does Shizuku take when she loses patience and is unable to move the relationship forward?
