The Second Year of Widowhood

A delicate little widow, naturally a bit absent-minded and unaware of her own beauty, meets two male candidates in the second year of her widowhood: the new emperor and her late husband's elder brother.

Her late husband is well and truly dead. The two male candidates are brothers who have been through life and death together, and they compete for her.

The female lead isn't a virgin, but the male leads are. I'll keep working on the blurb.

Theme: Don't wait until all the flowers have fallen to break off a branch.
