Recommendations stand-in leaving the scum

I am searching for a novel where our MC is a stand-in. when white moonlight comes back mc leaves the scum and got together with ml. After that scum will fall in love with mc but mc doesn't get back. MC needs to be a badass and strong personality. he should know his role as a stand-in and is not transmigrated or reborn.
it doesn't matter if it is BL or BG. I kind of want to read this kind of novel more than the one where the stand-in falls in love with the contractor.

(no dog blood or much drama) I don't need more drama in my life for now

 

Oho~ I have one in my tbr titled "The white moonlight stole the stand-in" smtg,it's BL btw.Cant guarantee if it has melodrama plot but I think it was tagged shounen ai. Idk :3

 

Well okay let me try. But I want mc to not be in any sort of relation with scum or white moonlight

This one comes close to your description. Difference is that MC leaves scum before white moonlight comes back. He turns him down right after transmigration.

Ah. Then I think this is not it. Ay.
The mc and white moonlight got together actually hehe~

 

Well I was debating to read it because of mc and white moonlight.

 

I have an interesting one, but it's kind of short
It’s Not Easy To Be A Stand-In (bl)
I don't think mc classifies as a badass, but you can still give it a try
