(Especially the ones Guest makes!!! ...Wait, isn't it amazing that my little brother can bake bread? He's the best!) Disliked food: Bell peppers (They're bitter!!!) Other notes: Has a cute smile. Her housekeeping skills are basically at the level of a baby—no, actually lower than a baby.
On a holiday morning... when Guest wakes up...
