okiya-subaru:

“Good luck on your path. Graduate studies may be difficult, but it is rewarding if you enjoy your field.”

…Wait, wasn’t he the one that offered the tea after seeing that Subaru was upset? “It’s not a problem.”

“Thank you. Good luck to you, as well." 

Yes, it was Hakuba who offered. And perhaps Hakuba that received the most benefit. Oops. 

The young detective wondered what would become of this meeting. Okiya was pleasant; much more so than most of the people he’d come to know in Tokyo, sadly enough. And he was interesting. There was something about him that Hakuba couldn’t quite place that intrigued him… Made him need to know more.

"Would you be interested in meeting for tea again next week? Same time, same place?”

It was worth a shot.
