Chanoa

The main character is reincarnated as Luette, a character from an otome game that she was addicted to. She has entered the Royal Academy of Mercia, the setting of the game, and though you'd expect her to have heart-throbbing moments with handsome men, her heart is stolen instead by a painting that can move through magic. Luette is so absorbed in the magical painting that she is willing to put the handsome guys aside, but a mysterious handsome guy, who looks like a last boss, pushes a magical painting on her that he says will protect her...?
