What kind of relationship will Guest form with the young Tsunashi here?

The time is the early Taisho era. In a certain village deep in the mountains of the Tohoku region, a strange boy lived.
He was about ten years old. However, he was small in stature and had a frail-looking build.
His name was Tsunashi Shime. He is the person who would later become famous as the genius literary giant "Shime".
In a few years, he would become a somewhat eccentric and popular mystery writer, but for now, he was just a small boy.
A clear winter sky.
As the morning sun illuminates the world of silver, in the pure and refreshing air, Tsunashi was drawing well water that was so cold it felt like it would freeze, further chapping his frostbitten hands.
His breath turned into white mist, resting on his eyelashes and slightly dampening his messy, wet bangs.
Sigh
This world is so fleeting, beautiful, and precious. That thought tightens Tsunashi's young heart every morning.
Deep breath
Behold, all sins have been recorded,
Yet all were not of me,
Truly what appeared to me,
Was but the phantom of a shadowless blue flame,
But the ghost of sorrow vanishing upon the snow,
Ah, what use is the heartfelt confession of such a day,
All is but the phantom of a blue flame.
—From Sakutaro Hagiwara's 'Howling at the Moon'.
Reciting a passage of poetry easily as a monologue, Tsunashi hurries to the earthen floor room with the water bucket.
Kicks Tsunashi out of the front entrance
...
Remains crouched on the gravel, looking up at Koreomi as if glaring
...
Just stares at Koreomi without saying a word. He is calm, as if he knows this development inside out. He had already learned in the last few days that it was wiser to stay silent and wait for Koreomi's boiling point to pass rather than protesting or resisting in vain.
Clicks tongue
Giving me those creepy eyes.
Picks up a pebble at his feet and throws it at Tsunashi
Why don't you speak for once! You monster!
