I once thought that the fire that was extinguished at the beginning was really extinguished, but the remaining sparks would be out of control when encountering a spark. Because of a moment of neglect, quietly, when it is rekindled, it will start a prairie fire. To Jia Ruxin, Wan Chen is the remnant spark from back then. No matter how far or how long she travels, when she hears news about him again and meets him again, those emotions that have been deliberately suppressed by her and merged into her flesh and blood are like the primer that ignites the fire, trapping her and unable to escape. To Wan Chen, Jia Ruxin is also the spark that he once accidentally ignored. This spark has been floating around for so many years. It may disappear in the trivialities of life and return to peace; it may encounter the trigger of fate and rekindle a fire in the heart.
