He loved her and gave everything he had, including killing his uncle, betraying his master, disobeying his biological father, having his head smashed by his third uncle, and being slapped to death by his grand master. But she still didn't love him. She claimed that she only married him out of anger, and in the end she ended up betraying her family and leaving her with no home.
He loved her, gave everything, gave up his youthful dreams, became a double agent, walked between light and darkness, and still protected her children after her death. Finally, he died tragically in Shekou. No one understood his love, his dedication, and his sacrifice.
When time goes back, when they meet, when they know each other, when they depend on each other, when they fall in love, then they know what happiness is.
