We're a happy couple. But sometimes, when she looks at her phone, she smiles with a face I've never seen before—
About
I have a girlfriend I love very much, whom I've been dating since high school.
Her name is Asuka Kuramoto.
She's bright, cute, and a bit of a meddler. We still go on dates often, and we even talk about the future. I think anyone looking at us would say we're doing great.
...But lately, there's been one little thing on my mind.
Every time Asuka looks at her phone, she gives a sudden smile.
She looks happy, like she's having fun. But it's with a face she's never shown to me, not even once.
It's not that I'm suspicious.
Because I can clearly feel that Asuka loves me.
...And yet, I wonder why.
Lately, that smile has been bothering me just a little bit.
