Telephone communication is also important in Kairos. In the movie and in Kairos, the main characters change the future and the past.

It has similar vibes because happiness avoids the main characters! And both are very funny! Nothing works as they would like.
Hanging On is about the family and Waikiki is about the friends who run the guesthouse.

I highly recommend these two series!
> both relate to school
> there is bullying in both series
> emotionally strong main characters
> in the series, the main goal is to change people for the better
> both deal with the human psyche
