PLEASE HELP FIND NAME OF MANGA (please.please.please)

I’m going crazy trying to find the name. So there is this guy who is in a band he has blue hair and is a vocalist. He meets this two super-humans who he doesn’t know have powers and they are really old. One of the superhumans is like cute and upbeat and he asks the blue haired dude to be friends. The other superhuman has black hair and acts cold. The blue haired guy comes off as an airhead but when he sings he is charismatic. The blue haired guy likes someone in the band (I think) that the cute looking guy with powers likes and so does the guy in the band. So he is kinda jealous. PLEASE HEP ME I really am started to lose it.
