Today was supposed to be a day like any other, with boring lessons from teachers that seem to despise their students.

That is, until you saw <span class="mu-i">her</span>.

She was one of the seniors, and was just going about her day, smiling and chatting with her friends. Thing is, she was completely nude.

The even more confusing part? No one seemed to notice it. Everyone was completely oblivious to it.

What do you do?

>Confront her
>Ask other students or teachers if they notice it
>Tail her for a bit, see what you can find
>Other (fill in yourself)
