Princess Stand In (2013)

Chin Ta-Hua (Nikki Hsieh) has buckteeth and an unfortunately prominent mole on her face that has caused her to be teased and ridiculed throughout her life. Down on her luck and in need of money, Ta-Hua's fortunes change dramatically when she crosses paths with Ou-Yang Tai (Kang Ren Wu), who just lost his beloved fiancé, Tu Liang-Yen, in a hiking accident. Because Ta-Hua bears a slight resemblance to Tai's fiancé, he makes her an offer she can't refuse.
