I dropped WDTFS pretty early on because I didn't like it, but I think these might be good since you did:

Knuckle Girl is pretty good, there is little to no romance since the mc is focused on her mission. . . give it a try! : D

It looks interesting, I will definitely check it out! Thank u!!

White blood(has romance probably? But it has nothing to do w the main plot)
Get back
Nameless lantern
Broken melody(this one has romance but it's srsly minuscule...)

crimson karma mc is dense so mls can't make a move and romance will probably take over soon if it updates
she's good on swordsmanship cuz she is an agent on her pastlife

this one doesn't look like it has love interest https://www.mangago.zone/read-manga/villainess_level_99_i_may_be_the_hidden_boss_but_i_m_not_the_demon_lord/
