Dear Ex

After the death of her former husband from liver cancer, Sanlian (Ying-Xuan Hsieh) discovers that the life insurance policy that was meant to cover the educational expenses of their son, Song Chengxi (Joseph Huang), was transferred to a different beneficiary, an actor-director named Jay (Roy Chiu), the male lover of Sanlian's late ex-husband who lives alone in an outlandish apartment and is still in the closet to avoid his elderly mother uncovering the truth about his sexuality. Following this discovery, Sanlian and her son ask Jay for explanations, but fail to discover the truth behind the change of heart of Jay's father. Sanlian it put in a difficult situation when her son, who she had hoped would side with her and fight for his rights to his deceased father's funds, shocks her by unexpectedly deciding to move in with Jay, and she must reevaluate how both men fit in to her life now that her ex-husband is gone. Song, on the other hand, is intrigued by Jay and decides to get to know the man his father spent the remainder of his life with. Though Jay seems distant and self-absorbed, he believes there must be more to the man that his father left his mother for.

Following the legalisation of same sex marriage by the Taiwanese High Court in 2017, 'Dear Ex' is a comedy-drama film that was co-scripted and directed by Mag Hsu and Hsu Chih-yen.
