looking for a guideverse webtoon!

I'M LOOKING FOR A GUIDEVERSE WEBTOON THAT I'VE READ LIKE MONTHS AGO, I BARELY REMEMBER IT I JUST REMEMBER THAT IT WAS SUPER GOOD BUT IT JUST STARTED GETTING UPLOADED SO I WANTED TO LET IT MARINATE BUT JUST NOW REALIZED THAT I DIDN'T PUT IT ON ANY OF MY LISTS AND DIDN'T BOOKMARK IT EITHER

okay so:
I forgot what the uke looked like bc he dies in the first few chapters and he's basically isekai-ed into another person that has the same name as him, it's been 5 years or so that he died but for him it's just like it was yesterday. seme has black hair and turns from a cutie to a bad bitch due to his captain's (uke) death. oh yeah and the uke was some type of high ranking commander or so and he was about you retire but because there wasn't a guide that matched the esper's (seme) strength his retirement was delayed and uh he died in a misson. oh and I think he had a bad/injured leg as well but honestly I don't remember much details oh and uke's friend recognises him in his new body due to the wave length of his guide powers?? something like that. gosh I hope that was enough info please help
