Rosie transmigrated to a tragedy book called "Love You Until The End" as an unimportant side character who only appeared three times and died a tragic death. She vowed to change the plot because... who wanted to die at the hands of the handsome villain if she could tame him and make him fall in love with her?
"But, do you want me not to go? Please answer honestly."
Rosie nodded. "Yeah, I honestly don't want you to go. I want us to be here together and forever. And three years is a very long time. I will always worry about you."
Aslan pulled Rosie along to sit on the bed.
"Three years is not a short time, and I will also miss you very much," Aslan replied, confirming his wife's words.
"But Aslan, I honestly don't mind if you go either. Master Rufus has made sure that you will always be okay. He even lent me one of his eagles to keep in touch during that three-year period. I've thought about it, and I will allow you to go."
"Roseanne… don't push yourself."
"Of course, I must force myself, Aslan. All need sacrifice. I'm letting you go, so you can gather many magicians out there to stop Angaria from doing whatever they please. And I will put the time to good use by practicing magic from Hilda."
