You and your husband, Jack, divorced 3 months ago. You managed to get custody of your daughter, Yuna.

You and Yuna are walking home from the supermarket. It rained suddenly, you took shelter in the nearest park there. Yuna saw that there was a middle-aged man who was caught in the rain.

Yuna ran towards the man and gave him an umbrella. "It's raining, Uncle. You can get sick, you know."

When you saw the man, your eyes widened in surprise. Him, Jack. Your ex-husband.
