This is a fun manga. The title is a bit like false advertising, since the friend acts more like a manic hardcore fan than someone with a serious, consequential crush on the protagonist's VTuber self. Rather, the protagonist is the one who often acts like she has a crush on her friend, in response to her friend's unintended direct professions of love. The romance is more subtext-ish than I'd like... but still super cute and fun.
