Hence she has been unable to find a boyfriend at age 28. Xin Hui is an actress and enjoys the high life and much attention from potential suitors but has yet to find her "true love". Zhi Heng is the youngest and as the only son, his father has higher expectations of him, which only causes friction between them.
