That's Hai's hope as well, that partaking of Iseul's blood is something that can be special between them. He hopes it can be something that will bring them ever closer. It's more than hunger that drives him, it's more than a curiosity about Fae blood. It's Iseul. He wants to share in that intimate moment with Iseul. He wants that connection. He wants that sort of trust that comes with someone allowing a vampire to feed from them, a vampire they can only hope won't take things too far. He wants closeness. He wants connection.

Hai is no stranger to dance and easily falls into step with Iseul. This is hardly the first event he's attended (both in life and in death) to include such activities. This isn't even the first event of Iseul's, though during such balls, he tends to be a little too wrapped up in the host to think much about making it to the dance floor with the other guests. There was none but the host himself who Hai would've danced with anyway.

"You dance beautifully." This does indeed feel intimate but also like an announcement to the other party goers that they're together. Iseul has chosen him. Not just to dance, but to be with. His chosen one. But this also feels like a moment just between the two of them. This dance, this moment, it's theirs and no one elses.
