It's a little lewd and quite glamorous. This is volume 5 in which there's a great upheaval in the Cinderella love story that started with a lie!

Yae and Takumi, who are enjoying a private trip in Dubai, decide to go to Adul's home, who's the third prince of the neighboring country and Takumi's acquaintance.

Yae's in a chastity crisis in the foreign land of Dubai!!

On the way home from a friend's wedding, Takumi told Yae that they should end their "sham marriage."
