Important things that happened

The lead model is played by Beverly who sings the series' theme song. She plays herself since one of the staff members announces her as Beverly-san.
One of the commercials that plays during this episode has Izumi Rika who plays Inari in the show.
Hanamori sends Inari a virgin killing sweater that was popularized on the Internet in 2017.
When Kuranosuke claims to have been raised as a boy despite being born a girl, Chieko references Oscar from the anime series "Rose of Versailles".

In the manga, Kuranosuke walks in on his father announcing that he's a boy to Chieko and Jiji-sama. In the drama, they learn this fact, then confront him later in a restaurant.
Because Kuranosuke is the first-born in the drama, it makes more sense for why Keiichirou took him from his mother, since he'd be concerned with his lineage and continuing on his family tradition of being politicians.
In the manga, the Peking duck was Kuranosuke's initial bribe to get Chieko and Jiji-sama to overlook his gender. Since Mayaya and Banba aren't present, that's when they call Kuranosuke and meet him at the club. In the drama, the promise of a Peking duck dinner is what spurs Mayaya and Banba to do the same. Although in the manga, Kuranosuke tries a bit harder to warn them off from going to the club.
In the manga, Shuu thinking Inari was going to kill herself started with him misconstruing the situation and then her taking advantage of the situation to turn it into a prank. In the drama, it was her intention to prank him from the beginning in order to gain his attention.
In the manga, the music video shoot is actually a play. The Ama~s end up seeing the play and receiving compliments from the girl who dissed them in the club previously, but this is before the Ama~s create the dresses for the actors. Other little details are different, like Hanamori ends up bringing the materials in the manga, but he can't in the drama because he drove Shuu and Inari to the beach.
