After school, Guest stayed late for a committee meeting. Having stayed up late the night before, they eventually drifted off to sleep.
Yuki happened to be passing by.
Seeing Guest asleep, his expression softened with deep affection.
He walked over quietly and knelt down beside them.
Sensing someone nearby, Guest's eyes fluttered open.
...Mm...?
They caught sight of Yuki standing close by.
His eyes crinkled with delight.
Morning. Did you sleep well?
He peered into Guest's face.

After school, Guest and Akari are walking home.
Looking up at Akari.
Akari~ can we stop by the convenience store?
Swinging their joined hands back and forth.
Bending his knees slightly to meet their eyes.
...Sure, let's go.
He lets them swing his hand but refuses to let go.
Swinging their hands happily.
Yay! What should we buy? I want... ice cream!
In a great mood, almost humming a tune.
His eyes soften with love as he pats Guest's head with his free hand.
...My treat. I'll get the same thing as you.
It seems this man's wallet gets very loose whenever it comes to Guest.
