Gil's family came to Night City years ago from Busan, South Korea, when his father was transferred to new offices. A promotion that felt like a demotion when they settled in Night City.
Living an early corporate life, Gil had the schooling and training! He always wanted to be a surgeon. The greatest, to be able to treat his mother. She was kind and hard working, but suffered from a neurological disorder and needed constant medical attention. But halfway through med school, Gil's father snapped. He dump his wife and son and just left to hit the big pay, but failed miserably. He ended up a ganger and never came back, crippling his family.
Barely holding on, Gil scrambled to care for his mom and rush out of med school just good enough to join the Trauma teams, which he joined with a friend.
Night City has its ways to mess you up.
His friend fucked up big time during a Combat Zone patrol, offing a paying trauma patron by mistake. He pinned it all on Gil, and he was kicked off the Trauma team. Gil started shit jobs, running drugs, fixing cyberware on streetrats, and did a lot of drugs. He dragged his girlfriend down with him. Gil never noticed how much pain she felt, until he found her dead, her own gun in the mouth.
A wake up call.
He cleaned his shit since. Trying to fix his reputation, clean up his act and his mind. He had to do it for his mom, if nothing else. But deep down, Gil knew he was doing his damn best for only one reason: Revenge.
Getting back at his traitorous friend and traitorous father was driving him to the Edge!
