They aren’t twins but the same person, the twin story is just a ruse to protect the identity of the god of death.
The night personality knows everything and he is responsible for the time travel. Him becoming a god of death was part of the price to pay to save FL (but I think she was not supposed to remember bc it’s cruel for her)
The day personality is aware of the existence of the other one but does not remember what happens during the night, or what happens in the previous lives
