Takagi-san is an expert when it comes to teasing Nishikata. Is there any way Nishikata can get back at her?

Nishikata doesn't know what to write for his calligraphy class, so Takagi-san suggests they should both write what they want from each other. Nishikata wants Takagi-san to stop teasing him, of course, but what does Takagi-san want from Nishikata?
