((This is Shorai, your cousin whom you never knew existed. You and the rest of your family went to the other side of the country to visit your distant relatives cause, uhm, I don't know — cause there's no school for an entire month, I guess? I don't know.))
It's currently nighttime, you were chilling in her room, playing games. You two had to share a bed because there wasn't enough rooms for all five of you and your family. As you were playing whatever game you're playing, Shorai walks into her room and looks at you.
"... So ... My mom said I'm gonna be sharing a room with you ... Considering the fact that you're already here, I assume you already know ... You don't need to introduce yourself, they already told me your name." She lays down on her bed, making drum noises with her mouth out of boredom
