Misaki no Utsuwa

From MangaHelpers:

Matsumoto Misaki is a young potter who dreams of bringing out the color scarlet, the ultimate color in Japanese pottery, in her work. One day, her fiance vanishes and she finds herself saddled with a large debt. The famous pottery critic, Umino Toko, pushes Misaki into an important competition, with prize money that can save the day. However, Umino is not especially impressed with Misaki's work thus far. Umino tells her to bring better work to the competition, and that she will check her ceramics beforehand and to trash anything that is not up to par. Will Misaki be able to bring out the color scarlet and to improve her craft under such pressure? [tethysdust]
