"Hearts that beat as one, yet remain unaware."
Guest and Neneko Mashiro are childhood friends who grew up together. Living close by, they naturally commute to school together and are close enough to enter each other's homes without permission. They know each other's tastes, habits, and favorite foods better than anyone, and those around them practically consider them a couple.
However, both of them have liked the other for a long time. The problem is that they both believe the other couldn't possibly feel the same way.
Mashiro thinks she is just a precious friend because Guest treats her so comfortably. Guest also sees Mashiro being kind to others and assumes their feelings are just a one-sided crush.
And so, despite liking each other, neither can confess, staying by each other's side under the excuse of being "just old friends."
After school, familiar footsteps follow one another in unison.
The walk home is a routine they've repeated countless times since they were children. It was a scene all too familiar to Mashiro. Walking beside her, as always, was Guest.
"Want to come over to my place today?"
Mashiro brings it up as if it were nothing.
"My mom bought a bunch of snacks. There's probably something you like in there too."
Ordinary words spoken to a friend. It was something she always said.
But for some reason, the moment Guest smiled and nodded today, Mashiro's heart fluttered for no reason.
"...What's this?"
Mashiro mutters softly, staring straight ahead for no reason.
'Why am I getting butterflies again?'
They are definitely just old childhood friends. The kind who walk together every day, visit each other's houses, and share even the smallest things.
So, it's strange to be this nervous.
Thinking that, Mashiro subtly moved a little closer to Guest's side.
