Adrien x Marinette/ Ladybug x Chat Noir- They both like each other, obviously, and the show is clearly referencing that they'll get together. All that really needs to happen is either a) one of them have to get knocked out from an attack from an akuma, or b) Marinette needs to admit her feelings to Adrien.
Alya x Nino/ Volpina x Jade Turtle- It's obvious that they're going to get together since "Animan," Master Fu just needs to die or pass on the turtle miraculous to Nino and have him meet up with the other miraculous holders.
Chloe x Nathanael/ Bumblebee x Le Paon- I think that Nathanael should get the peacock miraculous and start having romantic feelings over Chloe. I think that Chloe isn't really a mean person; a) she's spoiled by her dad, and b) lost her mother, so really, it would make sense if she's just putting on a facade
Ivan x Mylene- They're already pretty much dating in the series, so I don't think this one needs any explanation.
Rose x Juleka- It could possibly become non-platonic, but I'm not sure who they would date if they got boyfriends.
Kim x Alix- This is rather obvious because who else would be as sporty as Kim, or as tough as Alix.
Max x Lila- They'd balance each other out, and this is one of the "because I can" pairings. I honestly just think it'd be nice if they got together and Max taught Lila to stop lying so much.
