https://www.cmoa.jp/title/322487/ When she was cursed and left all alone in the world, an unusual cohabitation life began for Aria, a girl taken in as a disciple. Her heartbreak keeps getting worse thanks to one person: Lucas Bailey, a great magician who can’t put anything back where it belongs. Feared as a reclusive sorcerer living hidden away in an old castle, he’s a stubborn, antisocial man who speaks with oddly feminine wording. Yet behind that reputation, he treats Aria like family, and even gives her gentle kisses over her bandages while trying to lift her curse. Before she realizes it, she secretly falls in love with him… Thus begins a mismatched love fantasy between a disciple full of insecurities and a beautiful great magician.
