What's the story of the movie When You Grow Up?

The film tells the story of a little boy who has no warmth in his life and is eager to grow up.

"Wait for You" is a fantasy drama produced and distributed by Hongkong Universal Asia Film Co., Ltd. and China Yindu Agency Co., Ltd., directed by Chen Desen and starring Andy Lau. Twelve-year-old Guangzai is an unhappy child. He hasn't grown taller since his mother committed suicide. He always thought it was the fault of his father and his new mother, so he always hated this family and hoped to live alone when he grew up.

One day in the park, Guangzai met a silly tramp? , claiming to have refined a drug that can grow rapidly. The medicine mistakenly turned Guangzai into an adult in his twenties overnight. Guangzai, who grew up, was both surprised and happy, and finally embarked on a dream trip. Although he looks like an adult, he is still a child's heart at heart, so he makes a lot of jokes. Guangzai is determined to pursue his dream lover and teacher, Miss Li, and they hit it off. But time passes quickly with Guangzai, and his age is increasing rapidly every night. When Guangzi, the seed of love, felt uneasy, she also discovered the truth of her mother's suicide. Guangzai is eager to find an antidote while trying to find a way to find a warm home again.

What impressed me the most was that my father found Guangzai old, and Guangzai said, "I won't dare next time." However, life is only a few decades. Close your eyes, a day will pass, close your eyes, and your life will pass. In these short decades, how many times will we have next time? There is no rehearsal in life, every day is live! Only by firmly grasping your present time, living every day well and looking at the ups and downs in life with an open mind can you fully appreciate the fun of life and create your own unique and wonderful life!
