Long story short (IF my memory serves me right) he is a loan shark and would hound the brown hair guy for money, but he also had a crush on him. He would mentally and physically torment him and only confessed his feelings AFTER he learned that the brown haired guy loved the robot and wanted to risk his life for Monguu. Anyways, he tried to turn a new leaf (waaaay to late) and sacrificed himself to save brown haired guy. By sacrifice, he tried to beat up the other bad guys and they kidnapped him and injected him with poison that was supposed to kill him but the chairman found him half dead and thought he was an interesting dude and essentially “saved” him.
All in all, you really should read the main story. It’s great and the robot is hot af. ┑( ̄Д  ̄)┍

I haven’t read the main story cause I’m lazy. People keep saying the Mc is a rapist to the brown hair dude in a relationship with an android?can someone explain or give a lil background on each character and what they did in the previous story? Also how did the mc get heats?
