The Duke's Beloved Bride ~I Didn't Want to Become the Concubine of a Lecherous King, So I Proposed to the Strongest Duke in the Kingdom, and My Doting Life Started in an Instant~

The day before her sixteenth birthday, Aira, the daughter of an earl, is suddenly told she has been selected as a concubine of His Majesty. Small in stature and with a childlike face, she has apparently caught the eye of the Emperor in his harem filled with enchanting beauties, as he thought it might be nice to have a girl with a different look for a change. However, the harem is a terrifying place fraught with conspiracies. Someone like her, without any significant backing, would be eliminated in the blink of an eye. At a loss, Aira takes what could be called a reckless action: she proposes to the most powerful Duke in the country! Will Aira's reckless gamble succeed?! This is a doting happy ending story between an energetic, small animal-type girl and the strongest magician who solves everything through sheer power. The work is being serialized or scheduled to be serialized on Kakuyomu, Alphapolis, Everista, and Novel Up+ as well. Passed the first round of the 12th Net Novel Award
