Annessa	Jason's girlfriend, who claimed to be pregnant. Jason died while saving her.
Chae Eunha	An actress in LME. Famous as a fragile beauty. Sujin calls her a 'bitch', for valid reasons. Also hates the fact that her name is similar to her mother's name.
Chae Yeonha	Sujin's mother. Kind but can also be strict when necessary.
Han Seun	Seo Joojin's mother a.k.a Korean Karen.
Jason Fassbender	Male, 38, game dev, divor... yeah, you know the rest. Dead in his world, alive in another (relatively) young South Korean girl's body.
Kim Chunja	Sujin's friend since their trainee days. Eventually gave up and started working in a beauty parlor. Got swindled by her boyfriend and lost a fair amount of money.
Kim Eunji	A nurse in the hospital Sujin was admitted in. Kind and motherly—just Jason's type.
Kim Hantae	Sujin's father. Luck has not been on his side for the last few years. His business suffered a lot, became debt-ridden and his youngest son's sickness made things even worse. Poor guy.
Lee Beomseok	Sujin's younger brother. Lost his voice and hearing ability due to some virus neither Sujin nor Jason have ever heard of. Sujin wants to earn tons of money so she could cure him.
Lee Doyoon	Chairman of LME, the agency where Sujin works at.
Lee Moonsook	Female, 28, idol manager and... yeah, you know the rest. Almost died due to an incident, but had a foreigner ghost stuck inside her since.
Lee Sujin	Sujin's younger sister. Dislikes her elder sister who 'played around' while their family suffered. Still, she cares enough for her in her own way.
Lee Yoonah	An idol turned actress who Sujin was in charge of. Said to have extraordinary acting talent that was discovered by her former manager 'Midas Hand' Sung Jinwoo. She also has a crush on him.
Min Seoyoung	Sujin's friend since their trainee days. Eventually gave up and started working in as a bartender in a bar. Impress her enough, and the next drink would be on the house.
Nam Jiyeon	Seo Joojin's father.
Seo Hangul	Dude almost became Sujin's husband, but things did not work out and the marriage talk failed.
Seo Joojin	Midas hand. Has never failed in any assignment. Obtained a system after travelling back in the past. The true MC of the world.
Sung Jinwoo	PR division head.
Team Leader Park	A doctor in the hospital Sujin was admitted in. Wants to study Sujin's brain.
Yoo Joonhyuk	A Director at LME. Always tries to push his own relatives and acquintances into important roles. An absolute asshole.
