My Tiny Senpai's secret #1 (Pixiv Fanbox)

My Tiny Senpai sometimes seems happy and other times sad and sore, I wonder what will hide.

That night at the Shiori-senpai office he was in one of the offices with a Senpai of another department (curiously equally small as she)

On the next morning Senpai was a little sad so I bought her a pair of her favorite desserts.
