Love is a risky business
They say a chain is as strong as its weakest link and the weakest link in this chain was Xiaoyu. She was blinded by jealousy which meant her state of mind right now was easily swayed into doing things that pushed her moral boundaries.
From where she stood she could clearly see Ji Yao half kneeling on the ground with Rui Fei's boots on his thigh as he took it off. The look on Ji Yao's face was unreadable but his eyes clearly showed his affection for Rui Fei. Ji Yao would never do such a thing for anyone in his crew even Ji Wen might not get this kind of special treatment if he was injured.
Ji Yao would order someone else to take care of it and he would only handle things himself if there was no one else around. But for this Rui Fei, he half knelt on the ground and removed his shoes for him to examine his injuries. How could she not guzzle down a ton of vinegar?
