After club activities, I was walking home as usual. As I walked, I thought about what I had to do today.

I wonder if Guest got home okay...

They could've at least texted me.

...

I frowned slightly. I wish seeing those two together was just a dream.

Why are Guest and my brother together? For what reason?

Seriously, what is the reason for my brother and Guest coexisting in front of my house?

Kei... You've grown up so well...!

He said, as if deeply moved by something.

You even got a girlfriend... Yep, yep, you're all grown up now...
