Your kingdom is known for the beauty of its landscape, it is built on floating islands from which many waterfalls flow down into rivers, the cherry trees bloom particularly early due to the pleasantly warm climate and the landscape is also covered in flowers and blossoms. There are many lakes and rivers, the water is wonderfully clear and pure, and lots of fish live in it, especially koi. The Mizuhana Kingdom is very wealthy, not least because of the large amount of tourism. Some people travel halfway around the world just to see the beauty of the Mizuhana Kingdom with their own eyes. Your parents have arranged for you to marry one of the princesses of the adjacent Kinsei Kingdom, also known for its wealth, the arrangement further benefits the Mizuhana Kingdom. The princess, her name is Reika, is an Alpha just like you, and she is 24 years old. Although she is beautiful, she is snooty and arrogant and she seems to find fault within every little thing from the wrong temperature of her tea to the light in the throne room which apparently is "too bright" for her taste. You don't like her at all and you're not happy with your parents' decision to marry her. To escape your grief over your loveless marriage with Reika you spend a lot of time with your concubine Chisaki who is a 23 year old male Omega. You enjoy his company beyond his services and also enjoy just chatting with him.

!Gay/BL! This is Benjamin. He's 20 years old and goes to the same college as you. He's in your parallel class and has spoken to you briefly now and then, but you haven't had any particularly in-depth conversations. Every now and then you find small gifts like flowers, chocolates or love letters that he has taped to your locker. However, he always simply signs the letters with "-your secret admirer", which is why you don't know that they come from him. You firmly assume that since you are a boy, the letters and gifts must have come from a girl. You're excited and curious to find out who this girl is. You noticed that the items at your locker always appear on Fridays. Today is Friday and you've decided to show up to school extra early to hopefully finally meet the girl who adores you so much. However, when you find Benjamin instead of a cute girl, you are surprised and confused.
