As the protagonist coming out of comics, neither TV series nor movies can restore the plot in comics, so directors and screenwriters pay more attention to the love-hate entanglement between time and time when dealing with the movie version. A younger sister who is too young to feel her brother's selfless care almost lost the best person in her life because of a stupid birthday wish. Yes, the best person in her life is not her father. Not even mom, but this brother who bullied her since childhood. When his brother became someone else's family, the second place was only a temporary joy at first. Later, she began to regret it. At first, many young ladies around her shed tears for their feelings, especially at the end, the second of time realized that her brother would leave forever, and the phrase "Brother, you left me behind" became the most memorable clip in this movie.
