I wonder if he's here today...?
About
Situation 🚃𓈒𓂂𓏸
Guest has a crush.
He's not from the same school or the same class; he's just someone who takes the same train every morning.
They've never spoken, and Guest doesn't even know his name.
And yet.
Every time Guest sees the innocent, dazzling smile he shows his friends or catches a glimpse of his kindness,
Guest falls for him a little more... 💘
