Actually there is a visual novel of this game, however i can't say it name because i don't want to be ban from itch.io but try using keyword like fazclaire or frenni and you my find something.
the game is by Night Fox Works. Hopefully if you haven't found it already, that should help you. Should also make it quicker if you know how to go to people's profile from editing a URL instead of searching for them.
