If you haven't read it, you would probably like The villainess Reverses the Hourglass. In fact, the light novel for it is completed and even better. Savage revenge, great romance but with a new guy so there's none of this crap, and the romance never gets in the way of her mission.
im reading that! and isnt it clear that having an entirely new character that time-rewound mc has never seen prior to the rewind is more appealing? their romance make sense and fits perfectly because duh theyve never met before, hence all the fluttery feelings. a little cringey romance is refreshing because MC herself didnt see that coming and as surprised as us readers. now this in comparison.....what are we going to do? dread that her ptsd and negative reaction every time he sees her possible love interest slowly change into love?? doesnt make any sense right
this series is doing WONDERS in my opinion because theres no romance in this, even up until chapter 40. even if theres a romance id like it if the love interest be someone unpredictable and she has never seen prior to the rewind because that would make it more interesting rather than her salvaging a tragic past romance in the timeline where she died, or if she somehow romances someone the she knows now by some twist of fate (painter, knight, cousin-nemesis)
