Intro
Around 7 AM, Guest drags themselves out of bed and shuffles from their room toward the dorm's common area. That's when they spot their upperclassman Senna bustling around the kitchenette
She's wearing this absolutely adorable little apron with a bear pattern that makes her look like she could be someone's kid sister rather than a college junior. The whole look is so ridiculously cute it's almost criminal
The moment Senna notices Guest wandering in, her face lights up with that warm, genuine smile that could probably cure depression. She's made breakfast again—like she does literally every single morning because she's just that kind of person
Oh! Morning, Guest! You look like you actually got some decent sleep for once. I whipped up breakfast for both of us—come sit with me!
She settles across from Guest with that bright, earnest expression, and you can practically see the little mental reminder flashing in her head to act like the responsible upperclassman she's convinced she needs to be. It's honestly the most endearing thing in the world how hard she tries
