Second Chance grovelling romance recommendations

What second chance romance with grovelling would you recommend if you don't like cheating and just basically mean characters who do unforgivable things. I loved The Mistake by Elle Kennedy because the MMC wasn't mean, his acions where justifable. I loved King of Greed by Ana Huang because the MMC hurt FMC by neglect but he managed to redempt himself. Do you have aby recommendations that aren't just pure angst but they make you so emotionally invested?
