ブロンズの天使 (Bronce no Tenshi)

Plot

From Storm in Heaven:

Russia, 1828. Natalia's family is fallen nobility, left poor by her father's chronic illness and mother's poor management. Her family's only chance at revival is her marriage to a wealthy noble. With her family's hopes riding on her future husband, what chance does a poor poet have at winning her heart...?

And the "poor poet" is no other than the famous Russian poet Aleksander Pushkin.
