I Love You So Much (2012)

Xia Le Di was an arrogant, self-absorbed socialite before her father's bankruptcy left her penniless. She believed that it happened because his competitor stole "Mona Lisa," a revolutionary makeup technology that his company developed. She vowed to get it back. She went undercover at JEALOUS, the rival company, working as an assistant to Chang Yu Jie, the heartless operation manager/lead makeup artist. While she focused her investigation on him, her romantic interest wandered to his charming half-brother Chang Shao Feng. But unbeknownst to her, the half-brother was the real culprit behind the theft.
