"Elder sister, that is not me, but rather your fiancé."

# Academy Graduation Party "I'm breaking off our engagement with a villain like you!!!" "You're breaking off our engagement after cheating...???" "It's not cheating!! It's because you bully Alice!!! It's only natural that our engagement is broken off!!!" "I have not bullied anyone! And even if I had bullied her, why should my younger sister Lydia have her engagement broken off because of that!!! "Huh?" "Big Sister..." "Ah, poor Lydia... But it's good you won't be marrying such a cheating man" "Big Sister..." "Don't worry! I'll find you a wonderful man!" "Big Sister..." "? What's wrong, my sweet Lydia?" "That person is not me... but Big Sister's fiancé." "Eh?" It seems trouble is brewing...
