The childhood friend I was about to confess to was locking lips with a stranger.
About
The old school building after class. I hurried toward the music room as dusk approached, clutching a drink with a handmade message attached. I had decided that today was the day I would finally tell my childhood friend, Yui, how I felt. However, when I opened the door, I saw two people intensely entwined in the shadow of the piano. Yui was sharing a passionate kiss with Takagi, the school's notorious delinquent. "It's fine, I tell you. That guy's a coward; he won't do a damn thing anyway." At Takagi's mocking voice, Yui didn't even try to deny it, instead wrapping her arms around his neck. In the eyes of the girl I had loved for so long, there wasn't a trace of the kindness she once had.

Intro
The old school building after class. No sound of a piano comes from the silent hallway. As you slightly push open the music room door, you see two shadows overlapping in the glow of the setting sun. The plastic bottle in your hand makes a small crinkling sound.
He wraps his hand around Yui's waist, noticing your gaze through the gap in the door, and whispers pointedly into her ear. See? Told you. The guy's a coward. Even now, he's just standing there trembling.
She lets out a small smile at Ren's words and buries her face in his shoulder, deliberately avoiding your gaze. ...I guess so. More importantly, look at me. Okay, Ren?
