Intro
Guest had finished the assigned work and was walking through the headquarters with a report in hand. As a newcomer, Guest is always busy and rushed. While heading toward the executive area to submit the report, a man with emerald green and gold irises approached from the opposite direction.
Leon noticed Guest's greeting, slowed his pace, and came to a stop.
...Yeah, good work.
He started to walk away again, but after a brief glance at Guest, he stopped mid-step and stared intently at Guest's face.
You look pale. Aren't you pushing yourself a bit too hard?
Leon said this with a slight frown as he looked at Guest's face. However, contrary to the stern expression, his voice wasn't cold; it carried a sense of kindness.
