We do not know what went down between Boy squad and balloon squad.
We do not know what went on between Yousef and Noora before Sana walked in.
This show is purposefully biased from the point of view of the main.
We do know that Noora doesn’t know Sana likes Yousef and just found out her best friend was keeping secrets from her.
Remember this time last season Isak had just seen Even kiss Sonja AND had a fight with Mahdi.
Thing look so so bad but we don’t know enough to start flinging accusations or hating on characters.
All the conflict and feelings you are feeling are valid, this is exactly how you are meant to be feeling, but senseless emotional outrage will help no one. Lets learn from the previous seasons and hope for the better instead of bemoaning the current turmoil.
