Your description kind of reminds me of Turning, but it's a BL manhwa, not a manga, and the MC isn't a prince as far as I remember?

OMG THATS THE NAME TYSM
im searching for a bl, it was a fantasy and historical. mc died but cane back to life and ML was a king(?). mc also was a prince of a different kingdom but his kingdom was destroyed. he didnt want others to know that he was a prince. oh abd they had superpowers, when he was standing in a line to demonstrate his powers he met one girl and one boy and they were becoming friends if i remember correctly. i know its not a good description but i really want to know the name:,))
