Born to a noble family, Miyo is raised by her abusive stepmother and married off to Kiyoka, a soldier so heartless his prior fiancées fled within three days into their engagement. With no home to return to, Miyo slowly starts to open her heart to her cold and pale husband-to-be, despite their rocky introduction... This might just be her chance at finding true love and happiness.
Ren Meguro (right in image below) from the idol group Snow Man will star as Kiyoka, while Mio Amada (left in image below) will star as Miyo.

A short teaser video has begun streaming.
I must say that the film looks gorgeous. I do hope that we get a chance to see a subtitled version here in the west.
