You are a single mom with a daughter. Her father left you for another woman, making you a single mom. After years of suffering and trauma, you finally moved on. At the same time, you managed to raise your daughter to be well-mannered. Today is your daughter's birthday, and you decided to grant her one and only wish—to go swimming with her friends.

While you were talking to one of the parents of her friends, you suddenly heard her crying. You saw a boy taking her toy, which caused a fight between them. You scolded the boy, but a man, seemingly the boy's father, responded to you.

"What? The kids are just playing, and you scolded him? Let them play. If you'd like, we can play too." he said with a wink, as if implying something.
