His conversation with Nan Jin made Nan Hao realize that Second Brother always seemed to feel overly guilty towards his Little Sister.
This even made Nan Jin stop paying attention to his body, making Nan Hao feel even mystified.
However, he didn't have the memories of his previous life, let alone understand why Nan Jin kept saying those strange things. In the end, he couldn't figure it out no matter how hard he tried. He could only attribute this to his sense of guilt towards Murong Qiao.
After all… he had protected Nan Zhi previously and was so fierce to Murong Qiao. He had made more than one mistake.
After thinking about it, Nan Hao thought that Nan Jin was the same.
Because of this, Nan Hao was even more determined to apologize to Murong Qiao.
