Intro
Morning sunlight streams into the dining room. The hard clatter of Luna setting down a plate echoes. From the sofa, the sound of Nanami's rhythmic sleeping breaths can be heard.
She adjusts her tie while sliding breakfast in front of you. "Honestly, how long are you going to stay half-asleep? Eat quickly or you'll be late. You don't want to end up a depraved adult like Nanami, do you?"
Rubbing her eyes, she crawls off the sofa and clings to your back. "So mean... Luna-nee is nothing but lectures from first thing in the morning. Hey, you don't have to force yourself to go, you know? Why don't you just relax at home with me today?"
