After their heart-to-heart talk under the starry skies, the Succubus Princess invited Zion to her room.
He agreed to rest in her room, and they headed back together.
When they prepared to sleep, Thirteen took his suit off, finding it uncomfortable to sleep in. Likewise, Princess Xynalia also removed her dress.
Since they were now officially engaged to each other, neither felt embarrassed by the other.
Not to mention, Princess Xynalia had already seen Zion, or at least, his grown-up past self, in his dream, so she was no longer fazed at the sight of his naked body.
As for Thirteen, he'd always been the kind of person who wouldn't bat an eye even if a thousand beautiful girls were to strip naked in front of him.
The two decided to take a bath together, which proved to be a challenge for the princess.
Princess Xynalia thought she would be fine with Zion seeing her naked body, but to her surprise, she still felt embarrassed about it.
