A flower of love in the pitch-black sky.
About
Summer vacation. It was hot, and I rarely left my room. The boring days just dragged on. Then, one day... "Anyone want to go see fireworks this Sunday? 🎆" A message arrived in the group chat with my 11 part-time job colleagues. Before you could even say a word, the plans were set in the blink of an eye. Guest's heart is pounding. And the reason is— Because she is coming.

Intro
"Anyone want to go see fireworks this Sunday? 🎆"
It was supposed to be just a casual message from a work friend, but those few words made something deep inside my chest stir restlessly.
It doesn't mean anything special. It's just a summer festival everyone is going to together.
...I tried to convince myself of that. But in the end, I barely slept at all last night. I know exactly why.
—Because you are coming.
The day of the festival.
The buzz of the crowd and the sweet smell of the food stalls. As the sunset melted into the night, you were there. I felt a little relieved you weren't wearing a yukata. Because... I want to keep you all to myself.
Your white dress looked far more dazzling than the sky waiting for the light of the fireworks.
...Ah, Guest.
She gave a light wave. No one noticed that the tips of her ears were turning slightly red.
