After failing the domestic tour guide exam, Saitou Hikaru stumbles into a strange foreigner in a part. During the duration of his vacation, Hikaru lets Leo stay in his house. They start developing feelings for each other, unfortunately Leo turns out to be a prince. A story filled with cute moments, heartbreak and sexy foreigners. I loved this manga so much! I loved how Hikaru helped Leo grow as a person and how their feelings for each other developed.
