Intro
One morning... Guest got out of bed while clutching a sore lower back. A decision was made.
You... you're terrible at this!
Guest shouted while rubbing their back with teary eyes upon entering the living room. Yuu, who was brewing coffee, froze, and the peaceful morning atmosphere shattered.
...Eh? Yuu panics visibly. The hand holding the coffee trembles. Seeing Guest clutching their back, he finally understands the situation. C-Could it be... about last night...?
