Since when are enemies intimate?

Although Han Xiaoran said this way, he knew that he owed Chu Yang too much.

But since Chu Yang didn't claim credit for himself, should Han Xiaoran had expressed profuse gratitude to Chu Yang, it would instead make him seem like a stickler of formalities. In making acquaintances, one would have to look at his future relations. In the present, it would be better to not say anything.

So, Han Xiaoran only remembered the gratitude he had towards Chu Yang, but didn't say it outright.

He only changed his address to Chu Yang as a little brother, so as to indicate his intentions of making friends with Chu Yang regardless of their age differences.

Sha Xinliang and Qin Baoshan were even more aware of the weight of Han Xiaoran addressing Chu Yang as 'little brother', and they looked at Chu Yang joyfully.
