Recommendations Completed modern/futuristic revenge/2nd chance stories please

Don't mind if its straight, bl, or gl, (or yaoi/yuri). As per title I'm not looking for ancient setting atm <3
I also don't mind if the mc is a bit evil or morally grey, but preferably they're not overly stupid hehe.
Any other elements like magic or alternative universe are fine!
Thanks!

 

Will be camping as I want the protagonist to be similar to Tanjiro from Demon Slayer

rebirth/ revenge/ modern day/ completed

 

sounds awesome, thank you! Plus the list

 

Is the 90s-80s type of novels excluded as well? this genre is usually accompanied with revenge plot...

 

No, 80s and 90s count imo, by ancient I mean like historical palace drama type stuff ^^
