MK is an Orphan.

Gun me down on this theory, but it is possible.

Part 1: His parents are dead. "Yo, don't tell my parents I'm here." He doesn't want his parents, In heaven cuz their dead, to know that he has this bad life. Part 2: He hated his parents. So, Alphys is presumably his sister. She got so busy in her duties as the royal scientist, she didn't have time for MK. Long story short, he ran away from his family.
