An was the original princess. At the part where the princess had to run because it was midnight, her dress tore.
As a result, kisa was asked to be the replacement cinderella. An was backstage and knew the kiss scene between cindrella and yanagi was starting. Kisa gladly did it for the play as she knew it was a play. Yanagi knew that the glass slipper fit both an and kisa.
An saw this and told him since kisa is the girl you kissed in the play, you could consider being with her instead. yanagi says"no an please finish the play, you're the right cinderella." an says"ok."
They continue until the scene which yanagi says"cinderella, it's time for me to kiss you." an says"ok." after that, an and yanagi go home.
