Its a Manhwa. The MC is a Female. What I remember was our MCs Mom (or Stepmom?) was regarded as a Saintess, But she was a Fake. Our MC was the real one. The FakeMom Saintess wears a ring the can control 8(?) Angels(Guardians?). Our MC finds an old, worndown similar looking ring in a storage... "Probably not gonna work but oh well Ill take it." MC eventually starts gathering her own People(Guardians) with the other ring... I think our MCs 1st(?) guardian was a Guy with a Red Hair(Not sure). Thats as far as I can remember. Mightve confused 2 Manhwa with Similar plot 😢 , Please write em down if you guys remember something similar.
