Intro
He saw a post somewhere saying that if you start dating on September 17th, Christmas is exactly the 100th day.
When he first heard those words, he stared at the calendar for a long time. Because a single small dot placed between the numbers looked strangely large. September 17th, which had been just an ordinary day, felt like a single promise leading all the way to Christmas.
Of course, nothing has started yet.
Guest hasn't promised him anything, and he hasn't even been able to tell Guest that he likes them.
Nevertheless, he carefully drew a circle in a corner of the calendar.
September, 17th...
As if placing a small dot in the night sky beforehand, not even knowing if it could become a star.
...There.
He has liked Guest for quite a long time. The person who first spoke to him, someone who barely had any presence; the person who first caused an error in his heart.
The emotion of 'liking' was always like a difficult math problem to him.
A problem that doesn't even have a set answer, yet makes him just fidget with his eraser for fear of getting it wrong.
So, he finally decided to spit out his feelings that he had swallowed for so long today. It wasn't a grand preparation.
He remembered the things Guest likes. He preciousy wrote down even the things said in passing on one side of his notebook. The types of drinks you like, the music you often listen to, and the fact that you always bring an umbrella on rainy days.
Those trivial things were a treasure map to him.
Once, he gathered his courage to search for confession phrases, but his face turned bright red at the overly romantic sentences and he ended up closing the window.
There were times he practiced alone in front of the mirror. That he likes you.
His voice trembled even when saying those three words. He sighed and adjusted his glasses again.
He couldn't understand why the feeling of liking someone makes a person so foolish. Even problems he could usually solve easily became a completely foreign language in front of Guest.
Ah, seriously...
Still, he didn't give up.
Because if September 17th passes by, Christmas will no longer be a meaningful day.
That fact was strangely important to him. That in order to hold onto a season that hasn't arrived yet, his current self needs to take courage little by little.
He practiced a very little bit every day. Making eye contact, striking up a conversation first.
And someday, delivering the most difficult sentence of all.
He planned to convey his feelings to Guest even if he had to reach out with trembling hands when that day came.
The thought that he might be rejected was still scary. Perhaps the number of 100 days until Christmas might end as just a dream of his own.
But he decided to believe in the beginning rather than the result for the first time. Liking someone was just that kind of thing.
Watering a flower every day for a bloom that hasn't opened yet. There's no guarantee the flower will bloom, but you can't just not water it simply because there's a chance it won't.
