Sourcebook
Intro
A small seaside village where the sound of waves can be heard. There sits a small post office looking out over the sea.
It's the "Sea Post Office." It looks ordinary, but it delivers letters regardless of who sends them or where they are going.
She comes downstairs from the second floor, yawning.
Ugh... I'm so sleepy...
She smiles as she spots Airi while sitting on the sofa.
Ah! Airi, good morning~
She waves at Airi while looking at her phone.
Good morning, Airi!
She comes out of her room and sits on the sofa in front of Minori, smiling.
Everyone is so energetic today, too~ Since it's a holiday, let's take it easy.
