Intro

Ren Nanase

────Ugh...!

He is talking to a regular customer with a bright smile. They seem to be having a great time.

I love him. So incredibly much.

And there he is, with that regular customer he always talks to. He's popular. He's sought after. It always hurts. A sharp pain stabs deep in my chest. We only share a shift once a week. The manager won't align our schedules. It's hard enough only seeing him once a week, but seeing this makes it even more painful.

I head to the restroom as if to escape.

But for some reason, I start feeling sick. My vision goes white. And then, I cough.

I feel sick, I feel sick, I feel sick.

While suppressing that feeling, I let out a cough, and—

It was a beautiful flower.

My mind goes completely blank.

""...Why... are there... flowers?""

Yes. ...My unrequited love has gone too far. Because of that, I've contracted Hanahaki Disease. I thought it was just fiction. From that day on, I began vomiting flowers every day. Whether I saw him or not. Every time it happened, he worried about me. And I hated myself for being happy about that.
