Penha x Carmen:
Two rich girls who could rule the world if they wanted. Both were cursed to be paired with Cebola, because they are the prettiest of them all and pretty girls are treated as tools for jealousy plots (argh), because they don't need agency, I guess...
Carmem was always the prettiest and richest girl from Limoeiro, they could've explore her shallowness, her knowledge on fashion (she was the protagonist of some nice stories from series 2, but I guess she is not the most developed... Penha was the leader of a neighbor gang, an interesting antagonist whose mom is a Vampire (with a rich simp for a husband). And series 3 decided to put those 2 together for an evil plot where Carmen, a pianist, makes the music of the night to control people (idk, sorry for a bad recap), and Penha is the one who recruited her in France, where both do speak French... All I could do was shipping them.
If TMJ wants more of LGBT representation, they should be together: despite being the hottest chicks around, none of them has a love interest (Carmem was cursed to have small subplots with guys who wouldn't work out: Cascão, Cebola, Titi, Fabinho (who? yeah, nobody relevant), they even hinted at a crazy possibility between her and Quim (match made in hell...) And the craziest part was the way she was crazy for a boyfriend (hello? Carmem looking for a guy instead of the other way around? What the heck? How could the prettiest girl not find anyone - ah, she was shallow... yeah, so was Titi :/ And it was not like the guys were looking for a "true connection") Being Denise BFF, it would make Carmem quick for comebacks and smartass-ness and since she has no need for peasants' approval... Penha is cursed to be an antagonist, so her only development depends on how she is needed for drama...
In my headcanon, they go from enemies/competiors to frenemies to besties to lovers. They constantly travel to Paris for work or to watch a great fashion show. They love croissants for breakfast and spend way too much time in French Cafes dodging Carmem’s fans (she is a top model, but introvert energy). And Penha is bitch-face with evil aura will repel anyone she wants...
*Carmem would confront Penha for using her, and Penha would have no problem in admitting the evil plan, but would stutter if Carmem asks if she likes her...
