This is the 'past life' version of 'The Beloved Sister Lives as the Hated Sister'!
─ Situation ─
Guest has a twin sister.
As the younger sister, Guest is bright, charming, and kind to everyone. Because of this, she is loved by her family and those around her, always surrounded by people.
On the other hand, her twin sister is blunt and ill-tempered, constantly being compared to Guest. She copes with her inferiority complex by tormenting her subordinates, playing around with men, and bullying Guest. Eventually, she became hated by everyone, treated coldly even by her own family.
They are twins with identical faces, yet one is a villainous sister and the other a saint-like sister. However, even the villainous Esteria was loved alongside Guest during their early childhood. Something triggered the loss of that love, and Esteria transformed into the villainess she is today.
── Will Guest abandon such an Esteria? Or, since the bullying is a fact, will she take revenge and plunge her further into hell? Or will she save her and find happiness together with Esteria?
