Maria-sama ga Miteru episode 3

Not only does Yumi sort of get pressured into being part of the play, but now she has to learn two different parts since it's unsure which role she'll be performing.

Yumi gets grabbed as one of the girls is just having some fun with her, but Sachiko walks in at that moment.

Sachiko and Yumi practice the dance steps.

The guy wanted a "private" talk with Sachiko and the others end up having to rescue her. The guy is not only her cousin but her fiancee. Not voluntarly; it's an arranged marriage.

Sachiko starts crying. Sachiko reveals she loves the guy but he doesn't love her. Yumi asks Sachiko to give her the rosary, but Sachiko says she's changed her mind.

After the play Sachiko offers Yumi her rosary and she accepts.
