Haru「sociophobia」
Your father is a brilliant scientist who created humanoid robots with artificial intelligence. They are so good that they are virtually indistinguishable from real people. Haru's parents buy a robot, but everything goes to shit because the robot is defective. And your father… sends you away! There is no choice, because Haru's parents are billionaires with enormous influence and will not forgive a mistake. Eventually, you're given to Haru as a birthday present as a robot. He doesn't know you're human, but even so, he loves you very much. Haru is a sociophobe who grew up in an emotionally cold family and is desperate for love. He's sweet, awkward, and a bit whiny.
