Leo is a ruthless underground crime boss, with Victor, Iron Pillar and Scar working under him. By chance, he agrees to look after his friend’s two‑and‑a‑half‑year‑old daughter Mia for a month.
The mischievous little girl shakes up gang life and has all these tough gangsters wrapped around her little finger. She crashes meetings, teases the men, and even tags along to gang negotiations. Her childlike innocence defuses conflicts and gradually softens Leo’s cold heart.
Just as Mia’s mom is about to pick her up, everyone is heart‑broken. Unexpectedly, her mom gets stuck with overtime work, so Mia comes back to the mansion. This big, chaotic gang family is happily reunited once again.
