Happy Birthday in Mandarin

The inseparable emotional line, one is defending, the other is waiting. Xiaomi (played by Liu Ruoying) and Xiaonan (played by Louis Koo) were classmates in college. Every year on Xiaomi's birthday, Xiaonan would send blessings and sing a tone-deaf song to Xiaomi. They know each other and love each other, but Xiaomi has never been able to face the relationship between her and Xiaonan because of the shadow of her childhood. Xiaomi later went abroad to study. The two were separated but they still cared about each other in their hearts. On birthdays over the years, Xiaomi still remembers Xiaonan’s blessings. It seems that each of them has a different life, but the memories of that year are still there. In the end, Xiaonan told Xiaomi that she was about to embark on the road of marriage. Xiaomi was heartbroken, and she was so strong that she confessed her feelings at this moment. Even if they still love each other, there is no turning back...
