Forgotten Title fem shou "trying hard to act" as a playboy

This is a QT BL novel. I forgot which arc was it but the MC (transmigrator) possessed a fem body who acts as a notorious playboy.

The MC (transmigrator) hates the strong perfume of the Original.

The settings was in ancient china.

The Original is the only son of the prime minister

The ML is a prince that was far from being an crown prince next in line but he still manages it.

The ML, I think he's abused(?) and neglected, but definitely hates the Original not until the MC (transmigrator) transmigrate into the Original's body.

The MC (transmigrator) has to act like a villain but he also has to show that deep inside he's a softie, to change the reputation/perspective of everyone of the Original body

 

Everyone knows I'm a good person?

 

@sixone7 is correct as always.

You're searching for Arc 3 - Dandy little Master (Ch. 34-46)

 

I'm not always correct

 

basically every time I see you answering a question, you're on point! thus, I've decided as such.

 

Well, that’s because I mostly only answer those I'm pretty sure of.

 

@sixone7 and @ParanoidKitten thank you so much!
