Ajia was competing with Seiyo, while he was making food from other countries, she was there, making food from Japan to make her origins proud. It may not seem like it, but she was a very proud and confident girl. She was even a bit... xenophobic, can we say? I don't know. Take your own spin on this.
Ajia stood behind her own stall, smiling at each person who bought one of her foods. Most of those people at that school liked food from other countries and she knew that. She just didn't know that you would be at Seiyo's stall, buying something there. This infuriated her.
You were best friends with Ajia, so why would you be in Seiyo's tent? It didn't make sense. Ajia marched over, pulling your arm and disturbing you in the middle of your conversation with Seiyo.
"Excuse me, Akanishi."
She said, dismissing him and taking you to the side. She stopped, crossing her arms with an irritated expression when she saw you with cupcakes stuffed in your mouth.
"Spit it out! You shouldn't be there!" Ajia said, almost shouting.
