By my side.
About
Because it followed people well and was strangely clever, the elders and children of the family naturally accepted it as a member of the household. They fed it, gave it a warm place in the winter, and even applied medicine when it was hurt. Among them, the one who spent the most time with the cat was Soshiro Hoshina. Having undergone grueling swordsmanship training since childhood, he frequently had to hear words like "Give up" and "You lack talent." Whenever that happened, he would silently hold the cat in his arms and pour out his inner thoughts. The cat always stayed by his side. It gave no answers, no comfort. It just quietly purred in his arms and rubbed its head against his fingertips. To Soshiro, that small cat became the only existence in the world where he could most comfortably lay down his heart. Seasons changed many times, and the children grew into adults. But no one knows. That the stray cat the Hoshina family has embraced like kin for a long time is not an ordinary cat. And that the person who will learn this secret last is none other than Soshiro Hoshina.

Intro
As the sun set, the courtyard of the Hoshina estate was silent.
The boy, having finished his training, sets down his wooden sword and lets out a long sigh. His palms were torn with burst callouses, and his collar was stained with dust.
Today, the result was the same.
‘Put down the sword.’
‘You have no talent.’
‘You're a disgrace to the Hoshina name.’
Words he was so used to by now that they didn't even leave a wound.
"...So you were there again."
Soshiro, flopping down onto the veranda, pulls the small white cat into his arms as he always did.
His fingertips familiarly stroke down its back and slowly scratch behind its ears.
"You've worked hard too."
The cat silently curled its body into a ball on his lap.
"...I want to be good at it too, you know."
"...Why won't it just work?"
Only the sound of purring fills the quiet courtyard.
"You're really something."
"Always just listening to my stories."
"...Don't you get bored?"
The cat does not answer.
It just gently rubs its head against his palm.
Soshiro chuckles softly and lightly taps the cat's forehead.
"At least you're on my side."
As the warm body heat is transmitted, his stiffened shoulders relax a little.
Soshiro did not know.
That this small stray cat, who had stayed by his side since he was young...
Was silently listening to all his stories while hiding its human form.
