Do you ever think about how weird S4 was for Idriss? Like, before Sofiane came back, the guy was without either if his closest friends for a while.
So imagine you're the devilishly handsome Idriss for a second. First, your friend comes home, and your sister starts acting weird and everyone's dancing circles around each other and I'm sure it was fun to be the brother in this little dance.
And then, you meet this funny friend at a party, you're hitting it off and he seems cool. He turns to introduce his boyfriend to you and it's the friend who kissed you last year, immediately transferred schools, and hasn't talked to you since. And your sister knew about it, and your sister is actually going to school with this friend.
And then, your sister starts some drama in her friend group and all of a sudden your new friend and your ex-friend are fighting and it tangentially relates to your other friend dating your sister's other friend.
And then they somehow all figure themselves out and your ex-friend turnes out to have an MI and you feel super bad and you all hug it out at your sister's party
