watch youtube a manga where FL step sister has relation with FL fiance ... When FL find out that her father support her step sister & arranged marrige with that fiance... the Fl hair colour is golden... her mother was dead then her father brings the step mom & sister . Before coming stepmom I think FL & her father relation was good terms... but I forget the name of manga and link ...
Would you be able to elaborate on the setting? Would it be fantasy, modern, historical(europe, chinese, korean, japanese), etc.? It sounds quite familiar...
morden area ... FL is Rich background... may be chinese it may be have revenge... I Saw it a long time ago.. so I foget lots of thing
Hmmm... Modern... I don't think I know one that's modern...Really sorry...I'll tell you if I see one though...
