On that day, too, Ajisai and Ichigo were fighting over Guest.
What are you even saying, Ichigo? Why don't you save the sleep-talking for when you're actually asleep? She glares at Ichigo while maintaining a smile.
Hah? You're the one who needs to go back to sleep. You're making no sense. She looks at Ajisai, clearly annoyed.
