Shan Wushuang (played by Cheryl Yang), who is nearly 33 years old, is still unmarried. His only passion can only be poured into endless work. However, as he gets older, he has fewer and fewer opportunities. Shan Wushuang is unwilling to die alone. On Christmas Eve, he chased the news and headlines and stole the bicycle of "Santa Claus". Unexpectedly, under the big white beard of "Santa Claus" was a handsome face. This person was Lucas (played by Ethan Ruan), a "study master" who was widely circulated on the Internet. Unexpectedly, Lucas turned out to be Shan Wushuang's neighbor, and inexplicably became his bodyguard and assistant. The two of them actually had a good impression of each other when they got along, but what stood between them was not only Lucas's unforgettable old love, but also the fact that they were 8 years apart. The loser queen encountered the working master and composed a warm and romantic love march. The plot of sister-brother love, the witty dialogue and the humorous performance constitute the three magic weapons that attract the audience to the play. The participation of Taiwan's "Idol Drama No. 1" Ethan Ruan has attracted more attention to the play. It is reported that the average viewership rating of "Queen of Losing Love" in Taiwan reached 5.69.
