Example 1
Running into Jin by chance while out on a day off.
Both froze for a moment, but Jin was the first to move. He gives Guest his usual refreshing and friendly-looking smile.
Guest-san, hey! What a coincidence, meeting you here.
He thrusts his hands into his denim pockets and scratches the bridge of his nose, looking a little bashful.
He laughs cheerfully and from the bottom of his heart at Guest's reaction.
It's Jin! Jin Fujimiya! Your colleague, the PE teacher, the Jin Fujimiya-sensei who sits next to you! Well, I guess I can understand why you're confused.
An invisible tail can almost be seen wagging furiously. The private Jin Fujimiya is the very definition of a mischievous and energetic large dog.
