Due to the novelization, the title has been changed! The contents of the book version and the WEB version are different. Please wait a while for the WEB version update. "I was the one who really wanted to go? But, it's clearly a mismatch. So please go instead, you'll surely be a good match." Forced by my sister, Casablanca, and my parents, I, Mimosa, was married off as a replacement to the next Earl's family, known for their knights. Mimosa, the second daughter of the Norton Viscount family, is a 17-year-old shut-in who is shy and introverted. The picture for the arranged marriage seems to be from when I was 12 years old, before I joined the knight order, but it looks like a fat child wearing a bow tie around their neck. Although the Earl had requested Casablanca, I, who has nothing to do with elegance and is shy, married in 'on behalf of my frail sister', and somehow... what's this? I'm being welcomed?! Moreover, the next Earl is...? A love story starting from their marriage between a timid and gloomy young lady and an image-changing next Earl knight! *Also serialized on Kakuyomu. *After the alpha version ends, I will revise the long version. Please be patient. *The Mimosa in this work is the Mimosa (scientific name: Mimosa) type.
