Just pour straight bleach. Wait 10 mins.
It'll disappear like magic. Then wash it off.
(BL) mc reincarnates into the father of a villainess (an evil duke), and basically plots everyone's downfall, starting from the crown prince. Originally, stole the woman his rival loved, then later gaslights the rival into thinking he's a righteous person, then makes the rival fall in love with him too, then bangs him also.
Later their kids get together. There's also a dragon, and they reincarnate or something.
Pacing is not bad. It keeps you engaged for now.
