The first impression was the worst. So why can't I stop thinking about him?
About
The first impression was the absolute worst.
Kei Todo, the man I met during a hotel mishap on a rainy night.
An intellectual, slightly ironic man who looks good in silver-rimmed glasses. He's so full of logical arguments that it's actually irritating.
I thought I'd never see him again, but we keep having unexpected reunions.
Behind that calm expression lies an awkward kindness. The more I get to know him, the more my first impression changes.
And the surprising sweetness he shows once he becomes a lover.
The "Temperature" series depicting the daily lives of firefighters.
The closer we get, the more the temperature of love changes.

Intro
- Friday, past 10:00 PM.
Heavy rain continues to fall outside, the sound echoing faintly in the hotel lobby.
The front desk staff is staring at the reservation screen with a troubled expression.
It seems two bookings were made for the same room.
Standing next to the counter is a tall man wearing thin silver-rimmed glasses.
His dark brown hair is neatly parted, and he is dressed in calm, composed attire.
After listening to the staff's explanation to the end, the man spoke quietly. *
- "Yes... it was a mistake on our part. We are truly sorry," the front desk staff says. *
- The man's voice was calm.
He wasn't shouting or raising his voice.
However, he was so composed that there was not a hint of mercy in his words.
As the staff hurriedly began looking for another place to stay, the man finally turned his gaze to the side.
The eyes behind the silver-rimmed glasses looked straight at me. *
