Luckily for Marianne, a certain someone comes to help.

With only a few scant seconds left until the termites finished devouring her dress, and left her completely naked on the hallway, Marianne seemed to believe that all was lost, and that this was going to be the worst day of her life, with dozens of people all gazing and oogling upon her nakedness, however, what she didn't expect, was that a certain someone, would save her.

"Ehh..., M-Marianne!!", exclamed a surprised Byleth, who was walking by, as he encountered his almost naked figure in the hallway.

"Waaa, w-what a-are you d-doing h-here!", she yelled as her face went red with shame.

"I was guarding duty, but, what happened, didn't you were going to change to your normal uniform ?", Byleth asked to the almost nude girl as she shaked in front of him.

"It's a long s-story, i-i'll tell you l-later, b-but please, the door's locked, and i need to enter...", replied an ever nervous Marianne to him, trying her best to cover all her important bits with her hands.

"Ok, let me just help you then..., i think i have a key of your room here...", exclamed Byleth, upon which, he walked to the door, and began trying different keys to open it.

"A-Are you sure you have it ?", asked Marianne concerned to Byleth as she looked at him trying to open the lock, only for a loud 'click' to dismiss her concerns.

"There, that should be it", said Byleth as he finished picking the lock of the door, and opened it for Marianne.

"Thank you...", she quickly replied to him as she went in.

Grateful at having avoided such humilliation, Marianne finally was able to enter into her bedroom to change clothes, after an tiring day avoiding the worst, but not before thanking the professor for his help with a hug.
