I cannot find this story for the life of me.

I desperately need help in finding this story where MC is reincarnated into a game as the final boss or the villain which is this black dragon. He was hatched by the crown prince who was hiding the fact that he was an alpha, btw this is also somehow in omegaverse. MC had this dark blue-ish hair while ML had blonde hair. The artstyle is very pretty imo. I can't this story due to the great loss of mangago that deleted all of my saved story w/o tags. Any leads is appreciated. Thanks so much.
