By aiming for good deeds, it seems she has entered the Prince's doting route!? Countess Louise, who for some reason can see letters above people's heads, is trying to change the "villainous lady (ruined)" that comes to her mind and become a virtuous lady! However, when confronted by Sylvie, she honestly tells him the letters "Target, Second Prince (easy)", which sparks her interest and they become engaged. Furthermore, he promises to "change the letters to put your mind at ease"...!?
