It was a gorgeous sight for me to watch how beautifully the staff animated Yuki's face expressions from her fear in shock at learning Zero's horrifying truth face on through her blushing for Kaname to her tears of compassion while hugging Zero from behind.

Spoiler:

The drama was top-notch in the storytelling, since Yuki as of now has become inclined towards Zero through means of staying by his side in order to comfort him and ease his misery and sadness. Still, Yuki has ingrained in her heart her feelings towards Kaname.

I foresee a bomb in that three-way, tight relationship.

Yuki's still too inexperienced to sort out her feelings in order for her to make an everlasting choice upon who she chooses.

Things can no longer remain the same between Zero and Yuki now that she knows he's a vampire. On the other hand, the same circumstance applies between Yuki and Kaname.

The other vampires are becoming restless or particularly upset that their leader is going softie on a human for a reason, which they do not understand. Kaname reserves his motives for himself, but I know that he truly loves Yuki and isn't an obsession for him.

Kaname might had felt jealous that Zero, whom possibly the "Pureblood" regards as his biggest rival more than a nemesis, got first delivering the vampire's kiss to Yuki.

And things are beginning to get messed up.

Spoiler:

The other vampire clans are neither benevolent nor open to Kaien's idea that he runs a habitat where humans and vampires can coexist.

They already have dispatched an agent, and that person won't be overlooking any single incident even if Zero loses it by accident.
