Marianne got her old dress stolen when she was washing herself.

Having gathered her courage to do it, Marianne began to wash herself with the fountain's water to clean herself from all of the tea and cake stains that she had in her skin, something daring, considering that she was just in underwear in the academy gardens in the middle of the day, but she was about to do something more daring than that.

"I wonder if someone could see me from here", she wondered to herself as she continued washing in the fountain, only to hear nothing but silence in the nearby, upon which, she continued what was she doing, only to notice not soon thereafter that there were indeed some tea stains in her breast area.

"'sigh'", she sighed as she looked around her, "well..., i guess i will have to clean there too", she said to herself, for unless she cleaned that area, it would continue to bother her for the rest of the day. And so, once again, after gathering some courage, Marianne took of her bra, leaving her completely topless next to the fountain.

"Let's do this quick", she thought, washing her breasts as well as the rest of the body as quickly as she could. Unfortunately for Marianne, though, it was then in just that moment that she heard the footsteps of someone coming close towards her.

At first, she thought that they were from Byleth, who had returned with her new dress, but then she realized, by the sound of it's voice, that this person wasn't Byleth, and that it was coming towards her fast. Making her hide in shame behind a tree. "This is embarring!!", she thought nervously as she hid.

In that moment, she hoped that the person would just pass by the area, and leave her alone not soon after, but that didn't turned out to be the case, as the person in question spent a few good minutes in the area, "Please go away!, Please go away!", thought Marianne as she continued to hide.

After a few minutes there though, the mysterious person eventually left the area, leaving Marianne once alone there, "Let's get dressed quickly", she said to herself, walking to where she remembered she had hidden her clothes, only to encounter a little problem there.

Namely, that her clothes were gone, leaving her in only panties as her only article of clothing, "EHhhhhhhhhhhhhh.....", she muttered as she stared at the scene in complete shock, "L-Let's just hope that Byleth arrives with my new clothes quickly", she told to herself, in a effort to keep her spirit up in such dire situation.
