What's the title of this princess H-manga?

[Murakumo]

I'm trying to find a hentai manga series about a protagonist who is living normally but soon is told he is the heir to a foreign kingdom's throne and he is to take up the throne now that an accident to the king has happened and choose someone to be his bride; he is approached by many girls around him who want to get on his good side, including his school teacher, a tv reporter, and other girls and a childhood friend.
The manga has two volumes, but only the first one is released in digital (second one is physical only)

anyone know what it is called? I remember it being something like "hime" or "princess"
EDIT: title "Hime-sama Erabi"
