Aged up to after leaving lycee. Adrien is modeling full time for a while, Marinette is majoring in fashion, or something like that. Alya and Nino are on a trip around Europe.
Lonely Adrien/Marinette want to talk to their best friends but they are always busy having adventures and can’t talk, so they have to hang out together and there is Adrinette cuteness.
But Alya and Nino’s adventures are just increasingly bizarre. Like, maybe they start simple, like, “I would talk but there is a really cool music festival happening and I need to check it out.” but soon they are like, “Sorry bro, I have to break Alya out of a Turkish prison, I’ll talk to you later.” and “Yeah, Nino has been kidnapped by a princess who wants to marry him, I have to save him.” and “We found an ancient treasure in a temple in the jungle and we had to fight a immortal guardian, I’ll upload some pics later.”
And Adrien and Marinette are just like, slightly annoyed that they aren’t there to listen to their romantic difficulties.
