Jealous over some boy?!

Lan Xichen was called out to Yunmeng to come to a conference that has nothing to do with him or his clan. Interesting. Since his Wanyin invited him, and he could use the cover of business what could go wrong? Many things actually. One of them being an arrogant Young Master. This Young Master crosses his limits one too many times, especially in front of THE Zewu-jun. He clearly has no shame at all! But there's nothing Zewu-jun can do, so he must wallow in his anger alone, right?
