I can't remember the name of this anime. There's this scene where this girl with glasses is telling someone a story about how she liked this one boy, but was too shy to talk to him. So, she knocks him unconscious with a radish and has sex with him while he's knocked out. She ends up getting pregnant from the incident, and the two of them move out somewhere.

I've asked around numerous times, but nobody has been able to give me a satisfactory answer.
