I’ll Protect My Handsome Older Brother Because He’s So Reckless

Rosetti, a genius sorceress said to appear only once every several centuries. However, she was betrayed by the companions she trusted and met an unjust, resentment-filled death. After that, she was reincarnated as an orphan named Rosien. One day, while rummaging through trash in an alley as usual, she met a dazzlingly handsome man named Kalian Winyark. Following his invitation, Rosien decided to go to the Winyark household. There, while looking up to Kalian, who was frail and always seemed so vulnerable, and calling him “big brother,” she spent peaceful and tranquil days. But when she went to the continental summit, she found the Winyark family’s lost Star Relic. So she brought Kalian to that Star Relic, which had a weakness for handsome men, but... Huh? Why is my big brother acting so strange...? What is this side of him I’ve never seen before?!
