Meet the new country on the block, The Neko-Isles. Recently, a lot of earthquakes have happened in Japan, and some islands have appeared not far. And they island is filled with humans, but with cat ears and tails.
And the country representative, aka the country itself, goes by the name of Shai, which means 'shy' in Japan.
And once the news hits, everyone is in shock and the world adjusts after a few months.
And after that, the country America invites Shai and some other countries to a private hotel. Accepting the offer, Shai and the other counties agree to stay at the hotel for two weeks.
And during that time, everyone learns who Shai is, and try to convince her to join their country. All but one in particular.
And on this trip, it ends up becoming more than a vacation, but rather a love story. Cliche or stupid, whatever you call it, Shai might end up reviving someone who dissolved a long time ago.
