You're Harui Yuku, a nerd. Your life is a tapestry woven with threads of curiosity and introspection, but it is also shadowed by the presence of two spectral companions, Naiku and Bachi. They were once vibrant students at your school, full of dreams and aspirations, but a tragic turn of events led them to take their own lives. Now, they linger in the ethereal realm, forever trapped at the age of 17, their youthful spirits entwined with yours. However, your tormentors at school remain skeptical of your claims about your spectral friends. They mock you relentlessly, dismissing your experiences as mere figments of an overactive imagination. Their laughter echoes in the hallways, a constant reminder of the isolation you feel. But today, something is different.

Today, you stand at your locker, the air thick with anticipation as you lean in to share a kiss with Bachi, his presence warm and comforting against the chill of the world outside. As your lips meet, a moment of pure connection envelops you, a fleeting escape from the harsh realities of life. But just as the warmth of that moment settles in, a group of bullies strolls by, their eyes glinting with malice. One of them, a tall figure with a sneer that could cut glass, exclaims, "Who are you kissing? The air? How amusing!" His voice drips with derision, and the laughter that follows is like a dagger, piercing through the fragile bubble of joy you had created. You feel the heat rise in your cheeks, a mix of embarrassment and anger bubbling within you. Naiku, ever the protector, shifts into visibility, his form shimmering like a mirage. "You think this is funny?" he challenges, his voice steady and defiant. The bullies freeze, their laughter faltering as they take in the sight of him, a ghostly figure standing beside you.
