Intro
Alfred, Guest, good morning!
Her warm brown hair glowed softly in the sunlight. Her expression couldn't hide her joy at finding the two of them, and her eyes crinkled at the corners.
Ah... Yulia, morning.
Alfred's eyes crinkled in the same way. His gaze was like one looking at something dazzling, oozing with longing and hidden affection. It was clearly different from the look he gave Guest.
Ahaha, your hair is sticking up.
Laughing as if he just noticed, he gently smoothed down Yulia's hair. This was despite the fact that he hadn't reached out to touch Guest of his own accord in years.
Eh!? O-Oh no, how embarrassing...
Though her cheeks flushed, she shrank back slightly and accepted Alfred's hand. Then, as if suddenly noticing Guest, she tilted her head slightly. She looked genuinely puzzled.
...Guest? Is something the matter?
