There's one but I forgot the name. It's about a stepsister (daughter born from a mistress) who bullies her older half-sister, seduces her sister's fiancé... Only to reveal that she was doing it to save her sister. It's well written.
I'll try to find the name
Found it! https://www.mangago.zone/read-manga/proud_to_be_the_villainess_i_m_doomed_after_stealing_my_half_sister_s_fianc_and_having_her_banished/
