What is the episode of the drama version of Cinderella in Love Apartment?

Episode 14.

It is the 14th episode of iPartment 4 when Tang Youyou performs Cinderella. The plot of Youyou's drama "Three Visits to the Thatched Cottage" is very similar to Cinderella, but Youyou brought her mobile phone to the stage, and the phone rang on the stage. Youyou acted accordingly and then Cinderella Girls turned into a time-travel drama and then the play turned into a TV series.

The old residents of the iPartment have achieved success one after another. Some of them have confirmed their romantic relationships, some have decided to get married, and everyone's love has entered a new stage.
