[Crossover] How Can I Save the World Without Playing Tennis?

My name is Qiuye Rihe. Ever since I was little, my dream was to become an astronaut... Ahem, my dream was to save the world.

So, four years ago, I met a boy. He told me very seriously, "How can you save the world if you don't play tennis?"

I believed him.

And then...

Then, by the time I graduated from my high school chuunibyou phase, I couldn't help covering my face in embarrassment.

If I ever see that boy again, I'm going to grab him by the collar and smack him in the face with a tennis ball.

And then.

I started dating that boy.

Me: It really is the best =v=

Couple: Echizen Ryoga

Pure, wholesome fluff.

↑ Because even if I wanted to write a bad ending, I couldn't pull it off.
