I'd agree if not for Toudou having no feelings for her cosplaying friend. I think it's more probable that the love potion really just amplifies the feelings that someone already has.
This is so genius tbh, I love how it uses the traditional shoujo tropes you'd see from male leads without pandering to traditional yuri, but still maintains a uniqueness
Okai. She is definitely into Yuri. Cause like. She know how to feel good when doing lesbian sex. And judge how skillful her parnet is. If she is not lesbian I dont know what is?
I think it's more like the potion causes them to feel love for someone for a while, but once it wears off it's not like they forget being in love, and since they don't know it was from a potion, they just assume those are their honest feelings
