Since Evran (
Evren) is of Turkish origin, one could start searching there if you want to match the tone of the name.
Adalet (the meaning "to act justly" is fit for a protagonist being met with a difficult choice)
AdileAylaLeyla Yaren (almost anagram-like to Evran, if that could add something to the narrative/their relationship)
I never really have trouble with the names of characters, as much as it seems other writers have. I usually come up with a name and stick with it, unless I suddenly don't like it and change it.
