Looking for books with a really poor struggling mc who’s grinding under extreme pressure, money/power obsessed, AND DOESN’T GET SAVED BY A RICH LOVE INTEREST!!!

LITTLE TO NO ROMANCE!!!Lookings for books with a disadvantaged mc like rin from the poppy war, who works really hard to compete against the rich classmates/coworkers. I want them to be bullied, beaten, and shoved around untill they break. Eventually do better than everyone and get revenge. DO NOT RECCOMEND BOOKS WITH SMUT!!!!!!!
