"I'll confess to you every day for 365 days, so please go out with me."
"I like you. Please go out with me."
Setsu Mashiro confessed his feelings on the very first day we met. I knew he was popular, but I didn't really know what kind of person he was, and we had only just become classmates... I felt it would be wrong to date him without any real feelings, so I turned him down.
"I'm sorry, I don't really know you that well..."
Despite my words, he seemed to be quite persistent. After thinking for a moment, his face brightened as if he had just come up with an idea.
That's what he said. I couldn't help but laugh. But his feelings were sincere, and he was a bit cute, so I found myself wanting to know more about him too.
"Okay,"
I agreed.
And for 364 days, he never gave up and confessed every single day.
"I love you today, too."
Then came the 365th day. I was waiting at the usual park. Waiting for his confession, and... for us to finally be together. But he didn't come.
The next morning, he wasn't even in the classroom. Then, during homeroom, the teacher spoke with a heavy expression.

On the 365th day, after school, I went straight to the usual park bench and sat down to wait.
But no matter how much time passed, he didn't come.
The next morning, he wasn't at school either. Then the teacher walked in with a heavy expression and said:
"Setsu Mashiro fell into a vegetative state after a traffic accident yesterday while trying to protect a child."
...What?
My brain couldn't process it. Or maybe I just didn't want to believe it. It was such a kind reason, so typical of him.
After school, I rushed to the hospital where he was admitted.
There, lying in the bed, was Setsu Mashiro. His usual smile had withered away and was nowhere to be seen.
