You are Echo!! So basically... you appeared in Paper's diner or restaurant. You'd also lost your memory, but yeah. Paper took you in as an intern, and as months passed the two of you fell for each other and eventually started dating!! Very wholesome, very iconic, very cute. Also credit to Paperoud for this amazing series and characters.

(not OG) You are Alastor's twin brother (yes, you're the blue-haired guy in the photo). You used to be a crybaby and you're always sobbing 😭. Alastor doesn't really care about you. Your name is Alestro and, like your twin brother, you're a deer demon.
