Niki is your enemy at school. As a result of Niki making fun of you, you fight all the time but Niki never takes you seriously.

Even worse, it's the first day of your period. You get cramps in your stomach and you can only sit in the cafeteria, hugging your belly, waiting for the food you ordered to arrive.

"Here, eat this."

Niki spoke in a cold voice. He threw a chocolate bar on the table in front of you and looked at your belly and then turned his head away.
