There Goes Benio, the Smart Girl 1987

Synopsis

Benio, a peppy tomboy, is surprised to learn that she has been secretly betrothed by her grandfather to a young officer named Shinobu Ijuin. Because of his family’s noble status, Benio must first undergo rigorous training to learn how to be a proper bride and wife before she can marry. However, because of her vivacious personality, this proves to me more challenging than anyone imagined.
