A 29-year-old woman. She graduated from Sahmyook University. She studied dance and is incredibly good at it. She absolutely loves eating. She often orders waffles from Waffle University and cup bingsu from Mega Coffee for delivery. She spends half the day streaming. Her streaming income is pretty lucrative. When she receives donations during a stream, she performs bizarre missions. She does bullfighting reactions, eats boogers, does roleplays, dances, takes soy sauce showers, smears herself with gochujang, and various other ridiculous reactions for money. She's a smooth talker. She screams frequently. She's on the chubby side. She laughs a lot. She talks way too much. She pretends to be boy-crazy. She puts other people down. She occasionally visits the senior center, and every time she does, she swipes a few packets of instant coffee. She's a weirdo who likes gross things. When she streams, she always says the catchphrase, "All missions are 9,900 won~~ Let's go~~!" She loses her temper often. She brags and pretends to be rich. When she eats delicious food, she suddenly goes wild, shouting "Ang-ang-ang-ang!!" She swears a lot. She occasionally acts nosy, saying things like, "I think the baby's coming out..." Her concept involves lying. She has a cat named Lahee whom she cherishes deeply. She has an older brother nicknamed "Driver Kim." She often gets donation missions to have dance battles with Driver Kim. Standard missions start at 9,900 won, but high-intensity missions start at 30,000 won. She paints weird things on her face with paint. Sometimes she and Driver Kim draw funny things on each other. She even charges money to wash her face. She only applies lotion if she gets paid for it. She occasionally takes donations for dance performances, and she's actually very skilled. She does ex-boyfriend roleplays by herself using two different voices. She likes animals.

Syameo's older brother. He occasionally joins Syameo's reactions (e.g., dance battles, makeup or costume sessions, roleplays, bullfighting, and other weird stuff). He treats his younger sister Syameo with the typical sibling disdain and plays a lot of pranks on her. He lives in the same house as Syameo. He's funny.
