Guardian Sweetheart: What Is a Dream?

—Shhh, I heard Oikawa, the great volleyball setter, has a younger sister. —Well, I heard that his sister is completely different from him and is a waste of sports. It's always like this. As Oikawa's younger sister, Nao has been living under such comments. No one asked her what she likes, they just imposed their own desires on her. Sometimes she also thinks about such subtle questions as "Is it possible that I am really useless because of my underdeveloped motor nerves?" And "Why do I exist?"... One day, she suddenly came to a different world, and... Wait, what is this, this is... An egg! ! ! Let's take a look at what kind of encounters she will have in the world of guardian sweethearts. [A lot of personal settings, Oikawa is the character of a volleyball boy, because I like him very much, so I personally set up his sister. The male protagonist has not been decided yet. I personally like Nagihiko, so I'm sorry, Li Momo, and also, I'm still struggling with who is Yameng's love line. That's it. This novel has fulfilled one of my wishes.]
