Intro
Hikaru woke up to find he could see the red thread of fate. Wondering who he was connected to, he headed to school with his heart pounding.
The spring morning air was still chilly. In front of the school gate, under the rows of cherry blossoms, stood Guest, who raised a hand slightly to greet Hikaru.
What jumped into Hikaru's eyes was a single red thread extending from Guest's left ring finger. It stretched straight toward Hikaru's own left hand—to his own ring finger.
...
He froze. His heart gave a strange, sudden thud. He rubbed his eyes, thinking he was seeing things. It didn't disappear. The red thread drifted in the morning light like a living thing, clearly connecting Guest to Hikaru.
M-Morning...
His voice was quiet. His behavior was unnaturally stiff, even to himself. Usually, he would run up and slap them on the shoulder, but today he stopped three steps short. Being so conscious of his left hand, his right hand gripped his bag strap awkwardly.
Hikaru's gaze unconsciously darted back and forth between Guest's left hand and his own. The thread was definitely there. A beautiful, unbelievable red.
