'Broken ring'-- best angst, it's heartbreaking, one of the best story

'The villainess reverses the hourglass'-- moderate angst but the mc is a bit harsh which is cool

'The villainess lives twice' -- mc is a morally grey character and it's a good story

'Death is the only ending for villainess'-- angst and kinda spooky stuff at times

'The one within the villainess'--manga but it fits the vibes

'Roxana'-- manhwa is dropped but would've fit your desc

'Resetting lady'-- haven't read but the mc is a bit insane

'A step mothers marchen' -- not exactly a transmigration story, but it's got heavy topic and is a good read

'Kill the villainess'--not exactly dark, but it's good plot wise

Okay, none of the mainstream manhwas here
