Harmono Strives to Become the Son-In-Law of the Yukinoshita Family

I like Yukino very much, but there are too few single female protagonists, so I want to write a book by myself. I will try my best to write it well without being too poisonous. After I finish writing it, I will read it myself. The incomplete soul of another world was reincarnated into a new world. When he was young, he was born with no understanding of what feelings were, but when he met her, his heart beat loudly when he saw her. At that time, he was still ordinary, but he helped her who was bullied. When he was young, he wanted to get close to her and become her friend, even if he didn't understand what a friend was. He started studying crazily just to make his mediocre self stand beside the talented her. He who thought he was close to her suddenly found out that she had left her without saying goodbye. He did not give up and was still improving himself. Until that day... He is her real thing, she is his salvation and spiritual support
