This seemingly lofty noble young master is naturally none other than Wang Shouzhe's future brother-in-law, Chen Fangjie. The 'unremarkable' household general standing behind him is actually Wang Shouzhe himself in disguise.
Of course, both had already put on makeup, applied personally by Wang Mei. Although it wasn't to the point of being unrecognizable, unless someone was very familiar with them, they definitely wouldn't be recognized.
When Chen Fangjie first heard about this plan, he thought it was quite amusing.
There aren't many occasions where one can please their future in-law's relatives in such an interesting manner. Moreover, Wang Shouzhe inviting the Chen Family to participate in this plan was not something that could go unrewarded for their efforts.
Therefore, to play the role of a young master with his eyes high above, Chen Fangjie even brought out a robe custom-made for him by his family to hold up appearances before and after the wedding.
