Tragedy of The Chateau Cepage

France 1746. A party is held in a palace. Francis Bonnefoy age 26 meets Arthur Kirkland (age 23). Love at first time is truly possible. But one gets in the way. Francis gets insanely obsessed with Arthur to the point where it becomes unhealthy for both of their well beings.

"Ello, " he said in a British accent. The French man chuckled, upon hearing his angelic voice through his ears.

"Bonjour, " he replied back. A smile crept upon both of their lips as the hung out together, ignoring the damsels in the palace. But a sick feeling crept into the French man. Love. Love isn't bad at all, but this time it's deadly.

"I'll have you soon, darling... "

(Based on the Vocaloid song Tragedy of the Chauteu Chepage)
No I don't see France as somebody who would actually force himself on somebody. For the sake of the song, he had to be like that. I saw him fit for that role because the song took place in France and why not have a Yandere France.
