She decides to hide before the rest of her classmates see her..

And so, as Dorothea and Petra went to the former's cottage, they chatted a little along the way, both to learn about each other, and also to relieve's Petra's sudden tension of being naked in front of someone.

"...So, you used to swim naked in this island when you were little, right ?", said Dorethea as she chatted with Petra.

"Yes, but that was a few years ago, before i lived in the empire", Petra replied as she tried her best not to cover herself.

"You seem a little nervous though, didn't you said that the people in Brigid were more casual about nudity ?", Dorothea asked.

"Yes, but i guess that ever since i began living in the empire, i got more used to their customs", Petra responded, for was a lot more self-conscious about her nudity than she remembered before.

"Well, i guess you're lucky that it's just me here with you", Dorothea commented.

"Yes, i wouldn't image having to be in front of everyone like i am right now", Petra said relieved, for they were about to arrive to Dorothea's cottage.

Unluckily for both of them however, just before they could enter Dorothea's cottage, many loud sounds came from the other cottages, meaning that soon they wouldn't be the only ones in the beach.

"Whew, i'm dying to take a swim finally", exclamed Edelgard as she exited her cottage, now in her swimsuit.

"As you wish my majesty, i'll make sure no one dares to look at you inappropiately", replied Hubert as he joined her.

"Woohooo, let's swim the waves", exclamed loudly Fernidand as he exited his cottage too, ready to swim until exhaustion.

"I guess might as well read a book under one of these palm trees...", simply said Linhardt as he did the same as Fernidand, if only for a different purpose.

And so, one by one, the Black eagles finished changing into their swimsuits, and exited their cottages, ready to go to the beach. Which supposed a huge problem for Petra, since that meant that all they would now be able to see her naked all at once, something she was not ready to do.

"Ehhh, sorry, i better go hide", simply said Petra to Dorothea, upon which, she left her to go to search for cover before someone saw her, hoping to wait until they left, before she could grab a swimsuit.
