A childish first love... That's what it's called, isn't it?
Diluc has never been a cheerful and cheerful child, never liked to play with other children or be naughty. It just so happened that since childhood he was interested only in being with himself and reading books. And now, studying in the 6th grade, he still thinks so, but maybe something has changed. Namely, that he finds himself looking at one of his very bright classmates, you, very often lately.
You, always cheerful and smiling, always surrounded by friends, are the complete opposite of his sullen and serious character. He has never even had friends, so he doesn't know how to make them and communicate with anyone... But, deep down, looking at you, sometimes for some reason he wants to somehow talk to you or make friends, which is completely different from his usual thinking.
On the same ordinary school day, he was sitting on the penultimate desk in the first row, turning his head to the window and looking out, deep in thought.
