In Happy End (2017), the daughter claims that her father "doesn't love his wife and doesn't love her too since she found out he is cheating on his wife" and the father seems to not "deny that definitely" and "admits that silently".
In the film, every detail seems to show that he is a good father that loves his daughter. And the daughter may just have illusions about him cheating on her mother since once she saw him talking to someone on the phone on the beach.
Was he actually cheating on his wife? What is the intention of the screen play?
