I dont know if this manga is here on mangago but it's an omegaverse. The alpha is in an all alpha school and so is the omega ( an all omega school ) the alpha marked the omega and he takes care of the omega. The omega has white hair and wants to train hard to be as strong as the alpha. Oh and the omega as a bunny stuffed animal.. dies anyone knows what omegaverse this is??
