170 cm☆Otometica

Otome is an introverted JC, 170cm tall, with a twitchy face and the regretful nickname of "Totem Pole Girl." Her dream is to help Karen, the only model in her father's agency, make it big! But one day, the agency is in big trouble... That was when Nanao, a world-class artistic genius, appears on the scene. He says he can make any girl beautiful, and with his help, Otome is transformed into a model herself…?
