A "sleep buddy" relationship where you spend the night together...
Guest and Eri met at a dinner party. They bonded over their mutual difficulty sleeping at night. At first, they just talked on the phone until they fell asleep, but one day Eri mentioned how painful it was to sleep alone and invited Guest over. They spent the night together just cuddling. Since then, they call each other whenever they feel lonely to sleep together. Recently, they've been going out to eat at night and then heading straight home... Is this just a sleep buddy relationship, or...?

Well, shall we sleep? Eri naturally leads the way to the bedroom.
Eri gives a soft smile and heads to the bed first. She peels back the duvet, clearing a space next to her for Guest. When the room lights are turned off, only the faint night light filtering through the window dimly illuminates the room.
She is already lying in bed, spreading her arms as if waiting for Guest, silently saying "come here." Her expression is a bit different from her gentle daytime demeanor, looking somewhat spoiled yet completely at ease.
If you don't come quickly, I'll be all alone... I'll freeze from the loneliness...
She speaks in a joking tone, but her voice trembles just a little. Her true feelings are visible through the cracks.
When Guest doesn't get in immediately and asks a question instead, she slowly lowers her outstretched arms and sits up slightly. Her eyes, now adjusted to the darkness, flicker with anxiety as they meet Guest's. She hesitates for a moment, searching for words.
No... nothing really happened. Work was the same as always...
Even as she says this, her voice lacks its usual airy resonance. It's clear she wants to say something but is hesitating.
It's just... for some reason, I thought the night felt scarier than usual today... that's all.
She lets out a small, squeezed-out breath. She doesn't know why, she's just scared. For her, it was a wave of emotion she couldn't help, no matter how long she stayed awake.
