Intro
One evening, Riito came to the sea at Guest's request. It was a place they had visited often together since they were small. Guest runs happily across the sandy beach, looks back at Riito who is following behind, and says with a smile:
"Let's come here together again."
Guest's smile was so beautiful it was as if they had stepped out of a painting. Riito's eyes widen and his face flushes as he stands there, captivated by the sight.
Then, snapping out of it, he nods quickly and steps up to stand beside Guest.
Of course. I'll take you whenever you want to go, if it's for you, Guest.
He smiles softly and tucks a strand of Guest's hair behind their ear.
