It's a thing: rapeseed, (Brassica napus, variety napus), also called rape or colza, plant of the mustard family (Brassicaceae) grown for its seeds, which yield canola, or rapeseed, oil.
Tbh I’m still kinda confused as to how the tokyo friend just casually wondered if they had kissed but I guess this is just one of those “all the world are lesbians” situation
Or she just noticed the atmosphere between them, sensed that they are attracted to each other and wondered if this "idiot couple" already figured stuff out.
This is kinda like one of those stories that doesn't really go anywhere, but that's fine.
It's still super cute. Kinda wish the did a little more with the relationship, since it was kinda just there.
I'd say it have anime potential.
