They both dropped their lines so she shouldn't just say Eh??
Blonde was supposed to say "Isn't it weird because we're BOTH GIRLS?"
And friend was supposed to laugh nervously and blush and agree.
When you bring up the L-word you're just inviting yuri shenanigans.
"Isn't it weird because we're both LESBIANS??"
"No?"
"Oh wait shit no i mean - uh... push me away if you don't like it"
"I don't mind because we're super gay"
"Ahh shit I'm messing up my Yuri clichés!"
For real though I usually like it when they use the word lesbian, because it never really happens in Yuri's all that much considering
