Forgotten Title A bit R-18 danmei novel

If I'm not mistaken or mixed up with other novel the story is roughly like this:
MC is ML da shixiong, i think or ML shizun? I forgot, and they usually sleep together, just sleeping not do any "exercise" tho, then one day i forgot what happen but MC help ML to "release it"

At first i thought it was Every Day the Protagonist Wants to Capture Me
But i couldn't find that scene arghhh... or maybe it was the novel villain heal or something but i only read it till volume 2

That's it all i remember i'm sorry if the description is kinda vague

 

Maybe Transmigrating into a Mob Character to Rehabilitate the Villain Plan ?
Edit : Or The Scum Villain’s Self-Saving System

 

Yesss that rehabilitate the villain that one omg many thanks

 

Woah nice I was looking for that too (○ﾟε^○)
