Tsubasa to Hotaru

I'm Sonokawa Tsubasa - 15 years old.
Right after starting high school, I fell in love with a senpai who saved me when I was anemic at the train station. I thought it was a destined encounter, but after running into him every day I was rejected with one word: "annoying." (Cries) While being comforted by my childhood friend, Yuri-chan, who's the manager of the boys basketball team, I found out that Yuri-chan had injured her hand! So now I'm helping with her job as the club manager!?
