a marriage on my big sisters behalf

Kuze Kaede, the daughter of a long-established Japanese restaurant. My sister Aimi is both talented and does everything, and her father likes her very much, but she disliked the modest Kaede. Suddenly, the management of the Japanese restaurant tilted, and the hell of Kaede began. I was not treated as a daughter, and I was forced to help the house as a housekeeper. At that time, my sister has a marriage proposal with Nanaogike, who runs an IT company. Ritsuhito, the matchmaking partner, is good-looking and has money, but it was rumored to be cold-hearted and merciless. Kaede will get married instead of Manami, who doesn't like marriage. Ritsujin is going to marry his sister with a bad reputation, but he is gradually attracted to the humble appearance of Kaede.
