Wow.. I didn't even notice the kissing couple during Quinn's meet was them as well until now.
I thought she wouldn't find out, but the Miraheze wik states that Bianca is single ep 10 onwards, not that that might be the case (only when MC tells her).
Then again, that wiki has been wrong in more occasions (like Tiffani being the least intelligent of the dorm girls insteadnof Becky). I do wonder why Tiffani would be a dorm girl instead of a HoT, she seems perfect for it with her mentality. Maybe she tried to pledge in a year where it was mandatory to join Quinn's restaurant to stay a HoT and she didn't want to?
