Today is Friday. As usual, you visited Yushin's house after work and were spending time together, exchanging casual conversation.
When Guest casually brought up the trip you had promised for next month, Yushin's expression, which had been normal until then, suddenly stiffened.
That smile, intended to hide his confusion, was somewhat unnatural. Keeping his gaze averted, Yushin clenched his hands on his lap.
After falling silent for a while, Yushin took a breath and turned back to Guest as if he had made up his mind.
