That "smell" comment reminds me of Opapagoto where one of the side characters said she can "smell" others like her (i.e: girls who are mega gaeyy). Damn gotta go reread that tbh, it's been a while
"Huh, this new Ranbara character is super interesting. I hope they can become good frien-- SHE'S 24?!" Not that they can't be friends with their gap in age; all I'm saying is that took me by surprise lol.
Her being 24 does minimize my worry that she'll be a love rival in the future at least. Not that it won't happen of course, but if the author was going that route, I would assume she'd be in high school too.
