"I guess you've been suspecting, Nathan. I'm not.... Human."
Nathan was slightly shocked after hearing what Riya said.
'Okay, I knew that there was definitely something wrong with her, but I wasn't expecting this...' Nathan thought.
If this was the case, then that weird feeling he usually got from her was related to her not being Human.
"If she wasn't human, then I would've known, so what happened?" Nathan asked Siena.
He was asking Siena this question, because he remembered that when he was in Vina Academy, she once told him that Vampire's were able to detect other races through each of their unique scent.
Nathan pushed his sword closer to Riya's neck, and he kept his eyes on her, as he listened to Siena's response.
"The thing is that, not all races have a scent. Just like Celine who is an Elf. Elves don't have a particular scent, so they can't be detected, and it's also like that for some very few races," Siena said.
