Miraculous Ladybug

From the first time I heard this song, I thought of Marinette and her complicated love life. I feel like this song would be coming from Luka, one of her love interests, writing a song about Marinette, who clearly still has feelings for her other love interest, Adrien. Luka is also known for playing his guitar. In the original song, Olivia sings, "and you're probably with that blonde girl, who always made me doubt.", which makes sense because Adrien is blonde and also a famous model. Even though in the show, Luka supports Marinette no matter if she chooses him or Adrien, hearing this song from Luka's point of view would be awesome.

Amphibia

A lot like Luka, I feel like this song also sounded like Marcy in Amphibia. Don't act like you didn't see Marcy blush and giggle around Anne on some occasions. I'm not positive if this is canon, but I feel like Marcy would believe that she wouldn't stand a chance with Anne as her girlfriend. At the beginning of the chorus, Olivia mentioned red lights, which reminded me of their glowing eyes before the temples. The blonde girl in this situation is obviously Sasha. Since Sasha is persuasive, I could see how that would make Marcy feel jealous.
