my reading Xiao Xiang Zi, a cloud spirit In heaven, and Chu Kong mess up the red strings of fate by accident during their brawl. As a consequence they are sentenced to be a fated couple in the mortal realm for 7 lifetimes as a punishment for not getting along with each other. However Xiang Zi sneakily reincarnates without erasing her memory, and unlike Chu Kong, she retains awareness and uses it to her advantage.
