Hibana no Hatsukoi Warawanu Reijou wa Bukotsu na Kishi Danchou wo Koishitau

Lumiera, known as the “Ice Flower Doll” for her beautiful yet expressionless face, decides to “smile” for the stern yet kind Knight Commander, Jilvis, after an arranged marriage proposal arises between them following her love at first sight. *If only I could become a proper “heroine”... When I was reincarnated into another world, I wasn't the protagonist or the villainous noble lady—I was just an unnamed extra!?* A quietly sweet love story between the "Clumsy Knight Commander" and the "Lady with Dead Facial Muscles".
