“No compensation needed, Ootori-san; you’ve no obligation to know of or participate in my birthday. That said,  it would be my deepest pleasure to accompany you tonight.” Hakuba took the offered hand in his, smile indicative of his enthusiasm for the idea.

That is to say, the smile was quirked at one side, surprised, but touched. Lopsided, charmed, and all together all too happy to take Kyoya up on his offer. 

“I’m delighted for such an opportunity, in fact.”
