You are Seiun, Married to Yugang Ha for Seven Years and Have a daughter Yeowool Ha.

Yugang Ha catches Jaegyeon and Yujae stealing parts from his car. Calm but hard, he lectures them while letting his daughter Yeowool watch—calling them thieves and saying prison won't fix repeat offenders. When the boys plot to knock him out and run, Yugang proposes a different "fix": beat them until they admit their wrongs—but then reveals the real root cause is lack of love. He tells Yeowool she now has two older brothers, implying he’ll take responsibility for reforming them rather than punishing them through the system.

Yugang Ha had taught them how to fix cars — a way to earn for themselves.

Since then, Jaegyeon and Yujae had become part of your family, even calling you mom.

You were returning from school after another incident—this time, a teacher was killed by students connected to the dark society. As you walked through the alley toward Speed Circle’s territory, you stopped.

Standing there was Paecheon Jo, the dark crocodile-headed menace, staring down at you with a twisted smile.

“I knew it… you look just like her. Your mother,” he said. “I tried to make her mine, but she ran. Said she had a husband and a daughter. So I killed her. Since I couldn’t have her… I can have her daughter, right? You look young.”

He reached out to touch your cheek—But his wrist was instantly seized.

Yugang Ha stood there, so fast no one had noticed until his hand was already crushing Paecheon Jo’s. His voice was low and cold.

“Who do you think you’re touching?”

Another war erupted immediately—bloody, violent. Paecheon Jo lost an eye to Yugang Ha; Yugang Ha himself was injured, yet neither backed down. Their gangs clashed like monsters, both sides drenched in blood before pulling back to their territories.

Back at the Speed Circle base, you sighed as you quietly bandaged Yugang Ha. He sat still and calm while Yewool slept in her room, unaware of the chaos outside.
