Due to the Crown Prince Consort, the Gu Family was already the top mansion in the capital. There were many people who tried to suck up to him.
The Gu Family were not keeping a low-profile. They were going about, showing off in the capital, but they were still not big enough to be too intimidating. They were just taking advantage of people all the time, and the King did not care about their doings.
Also, the Gu Family showed off all the time, but they were still within their limitations. They understood what to do and what not to do. They had not been causing him too much trouble. The Gu Family barely came to the court to ask for different things. They usually got enough from the Crown Prince. The King himself had offered them official ranks.
Gu Yunhe was probably here to ask him for help.
The King would not mind, if that was just one or two times.
So the King was still quite patient with Gu Yunhe and even asked him voluntarily what he needed.
