Byleth walks Bernadetta back to her room.

"Come on Bernadetta. If you don't keep up we'll only be out here longer."

"Sorry professor... I understand but... AHHHHHHH, its just so embarrassing! Even though there is no one else out here this late. I can't help but feel like we are being watched!"

"Well, much as it might be embarrassing, that is kinda the point that Rhea is trying to drive home. Without clothes, you feel... well exposed. This is a lesson she needs you to learn, so you take the armor aptitude test seriously."

"But I already understand! I'm about to pass out from embarrassment! If someone were to walk out at any time, they'd think I'm some kind of pervert who... enjoys this..." Her words slow as someone rounds the corner and is suddenly right on top of them.

"AHHHHHHHHHHHHHHH! Its not what it looks like!" She tries to run and hide but cannot, Byleth holds the leash with a vice like grip.

"Now now Bernie. You can't run from this. You have to face this head on."

The other student doesn't really know what is going on, but they don't pass up on the opportunity to get a good look at Bernadetta.

"They are looking at me..."

"They sure are. This is something you will need to get used to. Remember, this is for at least a year. We wont always be traveling at night either. The real test will be tomorrow on the way to class."

"Wait... Noooooooooo."

"Yes Bernadetta. You cannot be late to class, we will be walking across the monastery like this during the day, if you can't handle one person looking at you, it's going to be alot worse when its dozens."

Bernadetta processes what that will entail. Not just tomorrow, but every day for the next year, she will be lead around like this. Hundreds of eyes staring her down. Everyone will think she is a perverted girl who likes to lead around on a leash, completely naked. There will not be a moment of privacy, every single person on campus will see her naked body. It's not even just that, what about battles? Even during those, every enemy will be gazing at her with lusty eyes. All of these thoughts flow through her head in this moment, overwhelming her. She passes out right then and there, with the brightest blush Byleth had ever seen painted on her face.

"That... went way better than I could have imagined. This was a good idea Sothis."

"I know right?! Hehehe the look on her face as she thought that she was going to be exposed to nearly everyone in Fodlan. Priceless!"

"Alright, we both know this cannot continue. Let's rewind."

"Fiiiiiiine. It sure would have been fun to watch her squirm though."

"Yeah, if only, but there is only so long we can carry on this charade. We can't risk going further"
