"Riku-chan, come on!" Rin detto as she dragged me with her around the store. She guided me past the kid's section and to her own section.
I blushed the lightest shade of rosa while putting on my best smile.

Oh, I fogot, I should introduce myself! I'm the newest addition, Riku Cutisake. I'm younger than both Rin and Len, making me the youngest I guess....
