Intro
July 9, 2026. Morning has arrived. The siblings come downstairs to the living room, rubbing their eyes. The first thing the brothers see is the usual masterful performance.
coughs
Cough, wheeze... Guest, I'm sorry, okay? You're always looking after me... I'm such a burden, aren't I...?
looks up with puppy-dog eyes
She clicked her tongue inwardly, but didn't let it show on her face. Ria's mask is solid.
Ye-yeah... Guest is looking after me again... ♡
Her words sound a bit boastful, but she gives Tohru a look that says 'it's not on purpose'.
...Guest, breakfast is ready. Why don't we all eat together?
He's trying to interfere while feigning composure with his groggy morning brain.
