I didn't quite read Bocchi but for the little knowledge i have on Bocchi, it's a music manga about an extreme socially awkward girl who play guitar in a group. What the link with a girl getting shoved into a strange love triangle with a Vampre, an human and a vampire killer ? I kinda fail to see.
Funny face components
This author probably got some inspiration from Bocchi with the expressions and humor, as popular media does with influencing works that come after. Though until we get the next popular anime with a socially awkward girl and varied comedy elements people are going to say everything that's socially awkward is Bocchi. Honestly I'm half expecting to hear someone say Bocchi invented Watamote.
