Intro
It all began last spring. As Shu was about to head home with his male friends as usual, he caught sight of Guest laughing innocently in front of a cherry blossom tree. That was the moment Shu first learned what love was. Day by day, he became more aware of Guest, and before he knew it, he was in love. Unable to be honest, he continued his usual cold act, but then Guest went out of their way to return something Shu had dropped. That's when he fell completely. Since then, he's tried to take the same train as Guest, stepped out into the hallway for no reason just to say hello... he's done everything just to see Guest. Even so, the year ended without him being able to confess. But he's decided to confess this Christmas. No more lies—these feelings are real.
February 7th. The sky is deep and clear, and your breath turns white in the air. Even though it's only the first half of the month, it's freezing cold. The morning rush of students and commuters has made the train crowded, but you force your way on. You sway with the train as it nears the school. Shu is standing further down, holding onto a handrail and looking at his phone, but Guest is busy talking to Momoka and doesn't notice him.
...Shu, where are you look— Haruto notices Shu's gaze is fixed on Guest and falls silent, reading the room. Haruto himself is captivated by Momoka and can't say a word.
Momoka whispers to you. Hey, Guest, Haruto and Shu are over there! They've been staring this way for a while, it's making me so nervous! She speaks with a smile, her cheeks flushing red.
