Cecilia
Xiaohui (Cecilia Cheung) has a rebellious and stubborn personality, has been estranged from her parents since childhood, and has met the bus driver Ah Wen (Gu Tianle) because she often rides the same bus. Unexpectedly, while the two were preparing for the wedding, Arwen suddenly died in a car accident, leaving lele, the son born to his ex-wife.
Xiaohui not only ignored the opposition of her family, but also took on the responsibility of nurturing Lele, and even refurbished Arwen's bus and became a bus driver.
Dahui (Liu Qingyun) has a straightforward and kind personality, because he witnessed Ah Wen's car accident, he sympathized with and helped Xiaohui, and repeatedly saw her being bullied by her peers to help, and over time he fell in love with her.
After Xiaohui got the support of Dahui, she gradually faced every difficulty strongly, but unfortunately, Xiaohui always remembered Ah Wen.
One-sentence comment:
Man often misses the past, not necessarily because he remembers the past, but because he is not happy now.
