mavet works with ennius (aka fate) to make sure people die according to their death clocks that he can see above their heads. if he prevents a death the balance becomes unstable and random people can die for no reason
so when mavet preventes one human kid from dying because he likes him too much, it causes strain on his and ennius' relationship, as well as mavet as punishment for going against his purpose
