Need help with the name of the Manga

So ever since this site messed up the bookmarked mangas and such I have not gotten anyone back so I am trying to find some thst I was reading but forgot the name of so right now im looking for a manga which I dont fully remember but this is what I remember of it right now

Not sure if it was yaoi or shounen ai but the mc lived in a city where everyone had to be perfect or something like that. the mc sneaks out of that city to an older part of the city with broken houses when he was a child to find his brother but he finds a deaf child who he starts hanging out with, the mc then promises to come back but when he was evaluated he was no longer perfect and was slowly losing his eyesight if I remember it correctly so he was locked in together with many other people who also had some kind of imperfections where they were forced to do labor. after a few years he was able to escape and meet up with the deaf boy but that boy though he got abandoned by mc and there was tension between them and they they were trying to get a car working to get away from danger togheter and there was two other people there to.
