It was a hot afternoon of June. Mamori, who still hadn't had the chance to eat her lunch, was simply hiding behind the fence of the swimming pool at her school, crouched down and eager to attack her bento box.

Mamori: "Itadakimasu. Heheh, seems like it actually turned out well today..."

She said to herself, looking at the food she had prepared.

Girl #1: "Oh? That's Wataya-san?"

Girl #2: "What are you doing out here? It's so hot today..."

Mamori, who got startled by being called out so suddenly by two girls from the Swimming Club, ended up dropping her bento on the grass, the food spilling out of it, and Mamori looking even more dejected.

Girl #2: "If you've got nothing to do, could you do the cleaning for us? We've got some stuff to take care of."

Girl #1: "Won't the teacher get angry?"

Girl #2: "It's fine, she's not the type to spill the beans, LOL!"

Mamori: "Ah... Okay..."

She said timidly, thinking she had no reason to refuse anyway, began to clean and mop around.
