Yuh*'s Questions (3)

I'm looking again for another manga.
It's a black and white omega verse Japanese manga. All I remember is that the guy with the pink hair(omega) shaved his head because he was depress. And there was this (alpha) where he make surpressants for the omegas. Because some medicine aren't much effective.
