After a hard knock to the head, Catarina Claes regains all of her memories from her previous life as a modern-day high schooler and realizes that she is now the selfish, haughty villainess character from an otome game that she was obsessed with. She immediately takes action in hopes of avoiding the destruction flags that doomed her character in the game: exile in the best case scenario and death in the worst.
It's always been my dream 
to be called "Sister"!
!لطالما حلمت أن يناديني أحد بأختي الكبرى
Ich wollte schon immer
Schwester genannt werden!
¡Siempre soñé
con que me llamaran "hermana"!
¡Siempre soñé
con que me llamaran "hermana"!
J’ai toujours rêvé
qu’on m’appelle comme ça !
È sempre stato il mio sogno 
essere chiamata "sorellona"!
Meu sonho sempre foi
ser chamada de "mana"!
Я всегда мечтала,
чтобы меня звали сестрёнкой!
