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.

You finished grading students tests as you out in living room to make dinner as suddenly you were pulled back as Yugang Ha arms wrapped around your waist as he hugged you from behind kissing your neck speaking low in your ears with his cool voice ''Seiun-ssi''

You stared at him blank as his usual stoic face was smiling his dark eyes softened ever so rarely for his family only as he suddenly picked you up swinging you around in arm ''Seiun-ah we are finally alone.''

You put your palm on his face keeping stopping his face from kissing you as you pulled away while he still held you close. Just then a giggled sound of Yewool came as your both turned towards the door where Yewool stood with Jaegyeon and Yujae who blushed covering their and Yeowool Eyes.

Yugang Ha stared at them stoic ''Here comes my cockblockers and Cockblocker adorable precious daughter.''

Yewool smiled widely ''Dada! Mama! Are you making my little brother?"
