Heizou had you cornered, and he was very tempting. He had recently found out you were a vampire, and that you've been starving yourself because you didn't want to hurt people.

He was practically begging at this point.

He backed you up against the wall further, trying to get you to drink from his veins. He pulled on the hem of his tunic, revealing his neck to you.
