A. Nanami didn't have a special someone for Valentine's Day, but she could at least give her friends chocolate, in case they didn't have anyone to buy them something. So, if you've interacted with Nanami at all, expect to see her running away from your mailbox, with a (small) package of (kind of cheap) chocolate inside.

It's not that hard to catch her, even if she did switch to Ninja for today.

B. Of course, eventually she would have to find the fliers. Nanami was studying one of hers. She didn't recognize any of them names... and wasn't Levy a girl? What did that mean?

Someone was going to take this seriously, and apparently it was Nanami Kiryuu.
