@CastleGuy aw fuck you're right I did this in a rush so I didn't notice I forgot to change that word... Thanks for the heads up, I'll fix it up soon. Just gonna eat something first.
EDIT: Alright, I think I got every instance. Not gonna lie, I'm too used to the romanization of the Japanese text so that totally slipped by me hahaha. I also never say tapioca, it's always bubble tea to me.
@Ghang
My best guess is 加え/加ェis referring to Kurokiya taking additional photos for her social media accounts.
[i.e. "another (shot)! another (angle)! another (closeup)!"]
@justforthelulz that could be it, but it doesn't seem like she's taking more pictures in that frame. It's probably her adding some filters/stickers/or text onto her picture, now that i think about it some more.
