A 2016 work: an old-fashioned, melodramatic, tacky Mary Sue story. It falls short in every way and is not recommended.
Jinjiang TV's exclusive blockbuster period romance Mary Sue drama:
Fifteen years ago, An Qingyu, the young fiancee of Crown Prince Jun Li, a handsome and distinguished heir of the Liang Dynasty, disappeared.
Fifteen years later, Jinsheng, the new head of the Tianshu Pavilion, a secret organization devoted to assisting the emperor, arrives in the imperial capital.
One day, the crown prince decides to search for the crown princess who vanished fifteen years ago.
Jinsheng: Your Highness, does the prospective crown princess have any distinguishing features?
Jun Li: She's beautiful.
Jinsheng: ...Does being beautiful count as a distinguishing feature?
Jun Li: Then I shall await good news from Pavilion Master Jin.
Ever since the cross-dressing Pavilion Master Jin arrived in the imperial capital and the crown prince exposed her identity, the two attendants by his side have been living in constant dread.
Qingya: His Highness is always sneaking into Pavilion Master Jin's bed in the middle of the night. What if His Majesty finds out?
Mozhu: If you don't tell and I don't tell, who'll know His Highness has been climbing in through her window under cover of darkness?
The Emperor: ...What are you two crouching here for?
*Set in an imaginary world. I'm a beginner, so please go easy on me.
Theme: Love is hard to understand
