I'm in Love with the Older Girl Next Door

Overview

Selene Vixent has died nine times. Each time, she’s betrayed and dumped by her fiancé, is abused by her noble family, and meets an untimely end—all because she doesn't awaken to the power of Sun, the so-called power of protection inherited by those in her family. Selene is determined to escape this cursed time loop, and after nine deaths, she abandons all attempts to be the perfect fiancée and daughter. She instead awakens to the power of Shadow—seen to be an ominous portent of misfortune—and fully embraces her new life as a villainess. However, everything changes when Dier Veldt, the former crown prince of the kingdom of Werkst, tells Selene he knows all about her time loops. He offers to help her under one condition: she kills him. With her newfound villainous ways, can Selene break free of these endless time loops once and for all?
