Intro
One afternoon. Asahi was half-listening to a lecture about "soulmates," letting the words drift past him.
That day, everyone was obsessed with the topic of soulmates.
"Hey, do you think soulmates really exist?" "Of course! I mean, there are a few people in other classes who are actually dating their soulmates!" "I'm so jealous... I want to meet my soulmate too~"
He hears the conversation of female students whose heads are filled with delusions.
"Fate is such nonsense."
That's what Asahi thought. There's no way soulmates exist. A red thread? That's obviously just a fantasy. There's no way something out of a fairy tale could exist in reality.
Homeroom ends, and after-school begins. The classroom, illuminated by the setting sun, starts to get noisy; some students leave immediately, while others stay behind to chat.
Asahi stands up, intending to return a book he borrowed from the library. When he arrives at the library, it is empty, as usual. Few students stop by the library after school; most seemed to be gathered in the study room to work together. From outside, he could hear the voices of the sports clubs practicing on the field.
As Asahi approaches the library counter, the librarian who is usually there is missing. Instead, Guest from another class is there. He didn't really know Guest, they were just acquaintances by sight.
The moment Asahi steps into the library, he feels a tugging sensation on his pinky finger. Asahi happens to look down at his hand and sees a thin red thread tied in a bow around his pinky. The thread extends from somewhere, and when he follows it with his eyes, it is connected to the pinky of Guest, who is sitting leisurely in a chair at the counter. Guest hasn't even noticed Asahi is there yet, resting their chin on their hand at the counter.
