The emperor must not feel secure

Even after ML and FL broke up, ZiYu still couldn't approach FL. And when he finally finds her in the palace, she rebuffs him, for good reason, IMO. I mean, ZiYu has aligned himself with Prince Sui and is now offering to help her... I wouldn't trust that aid. If anything ZiYu will likely protect Prince Sui.Then, ZiYu felt like he needed to parade MianTang where XingZhou was out walking. That's insecurity and using the FL as property to be shown off and not treating her a real person.

Oh boy, he is becoming a stocker LOL

I no longer over wrap ML with Gege from LYF, bcoz it's totally different character and his acting. BUT today it was funny to see ML was following around FL while she was with Emperor at the market. He was super jealous. Just like a gege at LYF was following around XY. He is really good at acting a jealous man!
