If Chu Xuan had another person besides his father who grew up with him, would he be able to leave traces of that "love" in the years of getting along with him? If that person was the only motivation for Chu Xuan to survive after his father's death, would Chu Xuan, who was said to have no emotions, be able to feel the emotion called "hate". Maybe people's feelings really depend on the person's soul, rather than the hormones in the body. Maybe years of companionship are really enough to leave traces in each other's hearts, and it is destined that two people who have no intersection with each other and are cold-hearted meet.
