Thanks for the mass upload!
There's still the whole thing where Chitose thinks his blood tastes better after another vampire feeds on him. And if she just wanted to see him flustered, I don't think she would have bothered with the smell fetish stuff either.
Then again, that could just be the author plugging in their fetishes.
Also, it seems Jiruji is into the hard to get type since she gets hot and bothered whenever Santa refuses her advances and doubles down on his feelings for Chitose.
Gotta say, for an ecchi harem this has got some nice hooks.
