Ester is happy to be starting high school, but trouble begins when she discovers that her ex-boyfriend Kaj has also enrolled in school with the goal of getting back together. With all her peers supporting Kaj, Ester befriends Vanda and they pretend to be a couple to win acceptance from classmates and Vanda's parents. The plan works at first, but their newly awakened emotions soon start to complicate things.
Unfortunately the movie Kaj + Ester Forever is not yet available on HBO Max.
