Would You Like Some Potion Milk Tea?

[One-on-one Western fantasy, both leads have no prior romantic experience] A young witch was eager to complete her race's mission, so she had no choice but to find a suitable sucker to father a child, then leave him behind. After giving birth to a daughter, the witch could finally go out and start a business! She opened a milk tea shop, selling milk tea, desserts, potions, and more. Her little daughter stayed by her side in their tiny shop, helping out and getting into mischief. Then one day, a hero opened the door to the milk tea shop. The hero had once been rescued by the witch when he was young, and the lovestruck boy fell in love at first sight. From then on, he carried one person in his heart. Years later, they met again, only for her to disappear without a trace after one night together. The hero searched and searched. When they met again six years later, the lovestruck hero looked at the three-year-old miniature version of the witch and felt as though the sky had fallen.
