This review may contain spoilers. I can handle the truth.
i didn’t understand why in the end alex’s sister seemed mad at her father and ran away from him when she just found out that during the berlin wall he wanted to see and hear about her and alex. because of that and her attitude i didn’t like the character of ariane. btw apart from this and other plot holes like the reunion of christiane and the dad in the end, i liked it very much. I LOVED alex’s friend
