Sita, Rama, Lakshmana. This image illustrates where, in the Ramayana, they see a deer of unearthly beauty and Sita asks Rama to get it for her. Rama and Laksmana doubt it is a normal deer and guess it is a demon disguised as a deer.
I think this is a depiction of Rama and Sita. Sita was kidnapped by a demon king, Ravana who tried to seduce her but she refused him. Rama rescued Sita but he's a flawed hero because he questioned his wife's fidelity twice and after the second time she left him.
