what should i name caelus?

i have been playing genshin for a few months now and i love it but i am up for a change so i downloaded star rail but i'm indecisive af so i have been staring at the "changing receptacle codename" screen for like 20 minutes now

my two main choices are to either stick with his Caelus, his canon name or call him "Ethan". i have always loved the name Ethan and i think it kinda suits him but i would love some suggestions (maybe what you named or wish you named him) just to keep my options open

and yeah i am probably overthinking this but i don't want to regret it later so advice would be appreciated
