For Titania, even if she had met Egan once before, he was not aware that she was actual Nia. So... this was actually their first meeting after all that blind dating over the years.
When Tania decided to finally meet Egan, she did not visualize this kind of first meeting. She still remembered that he called her a female toad once. Even though most of the time Titania's unearthly beauty brought her nothing but trouble, she still felt grateful for her beautiful face because she too was a normal girl who was vain for beauty and wanted to flaunt her prettiness in front of her lover, she wanted to rub it in Egan's face leaving him in awe when he would first see her. But now, when they were officially meeting for the first time, she was in such an embarrassed state that it definitely could not be considered the beauty of a heavenly fairy.
