How I imagine the in-between parts of the Love Square would've gone if the show went with PV:
(I don't know the exact details so some parts might be wrong) Ladelix (Ladrian): Ladybug is so happy Felix is paying attention to her. Felix is relieved Ladybug isn't avoiding him. Felix is more likely to get a kiss from Ladybug, but bad luck or plot shenagagians stop it from happening. Felix genuinely seems to respect Ladybug or grow actual feelings for her thanks to seeing her outside of Chat Noir.
BridgeChat (MariCat): Probably similar to canon but Bridgette is nicer than Marinette. On top of seeing each other as their 'true selves', there's the added bonus of:
Chat Noir: Hey this girl isn't so bad when she's not falling over herself to confess her feelings to me.
Bridgette: Hey this guy isn't so bad when he's not trying to seduce me.
