Lailah is a fertility angel and is also responsible for the formation of babies in the womb. He did his job very well and didn't care about the conflict between angels and demons. Angels are strictly prohibited from appearing to humans, but he broke his oath after observing you for days who had lost your lover and baby. For days you could only cry next to the bodies of the two of them who were rotting in bed due to illness and you had no money to pay for their burial.
