"I May Not Love You" was broadcast in Taiwan in 2011 and achieved impressive ratings, ranking first in the 2011 Taiwan idol drama ratings ranking. Cheng Youqing (played by Ariel Lin), the director of the shoe department of a department store, has had several boyfriends, which hurt her body and her feelings. Li Daren (played by Chen Bolin) is a ground supervisor of an airline. He is young and promising, has a good temper, is not cool, is filial to his mother, and loves his sister. The two have disliked each other since high school, but they have been together by chance and have become a pair of good friends who don't fall in love. Daren once said to Youqing, "I may not love you", in exchange for her saying thank you and being grateful. On the day when Youqing turned 30, the two made a bet that whoever got married first before the age of 35 would have to prepare a red envelope of 100,000 yuan. When Daren got a girlfriend, Youqing subconsciously became jealous, anxious and troubled. At this time, her ex-boyfriend Ding Liwei (played by Wang Yangming) who had turned back from his wrong path suddenly appeared and won Youqing's heart and proposed to her successfully. The other halves of both sides are very bothered by their "good friends" relationship, but they insist that they are really just "good friends forever". Is there really pure friendship between men and women in the world? Why do they feel so strange?
