My sister, who was my enemy, loves me

With beauty, noble blood, and genius talent—my sister had it all. Born as her rival, it was only natural that I ended up dying by her hand. I ran away once, but half the empire turned to ashes. So, I gave up and let myself die. Shhk— The moment her cold blade touched my neck, I returned to the past—as an 8-year-old. “What the heck! Do I have to die again?” In this life, I swore I wouldn’t go down so easily. I clenched my little fists and vowed to survive. “Harper, my little sister, even if my dream is shattered, I want to protect you.” …Huh? “To think someone would try to harm you again inside the Lupherne mansion... The world is truly full of madmen.” My sister… had changed. A lot.
