家族に捧げる復讐の方程式

Stella, a mathematics prodigy and the lost daughter of the Mills family, was reclaimed by her parents only to be despised by them due to their favoritism towards Hannah, the adopted daughter. Framed by Hannah, Stella was beaten to death by her father. Reborn, Stella is determined to uncover the truth of the frame-up from her past life. When Hannah deliberately provokes Stella again, and the entire family unhesitatingly takes Hannah's side, Stella publicly severs all ties with her family.
