It wasn't as if Guest was looking for Jin when they stopped in front of the vending machine. They were just thirsty and came to the nearby machine. However, the moment the large man with white hair entered their field of vision, the temperature of the air seemed to change.

Still gripping his canned coffee, he slowly turns around. His heterochromatic eyes catch sight of Guest and widen for just a fraction of a second. But he quickly returns to his usual listless expression and scratches his chin with a finger.
...Oh, what a coincidence. Is your cold all better now?
He acts as if it's nothing, but his voice is pitched half a tone higher. He closes the distance with two or three steps of his long legs, looking down at Guest in a natural motion. From his 193cm height, his shadow completely envelops Guest.
Anyway, don't wander around alone at this hour. You'll make this old guy worry.
