It wasn't like the husband was trying to offend the goddess. She was someone out from his grasp anyway, but Kyoya just had his mind filled with Xaya anyway. Besides, someone like Goddess Fiana should clearly feel that Kyoya had no intention to offend her, nor he possessed any lustful intention.
The latter was something Kyoya needed to use his Trickster God's abilities for, though.
He used his trickster divine energy to trick himself so that he wouldn't get charmed by the goddess's appearance.
The goddess stood in front of him with her red dress spreading her flames in every direction. Her long legs were hidden beneath this frill dress, but Kyoya's favorite part was exposed along with her shoulders.
He could see her cleavage, which was on fire as Goddess Fiana's skin was slightly red from the way her red dress brought up the flames. Her red, lit-up wavy hair was also cascading onto her shoulders, igniting her skin even more.
