Protecting Your Sweetheart: a Green Plum Falls from the Sky and Turns into a Bamboo Horse

[Also known as "Fujisaki Naghiko's Observation Diary" and "The 21 Days I Met Her". The male protagonist Nagihiko Fujisaki is the main perspective, and the female protagonist is Saki Fujiwara (Shen Shuqing), a Chinese-Japanese mixed-race complainer. It is based on the guardian sweetheart novel in the previous book, using the third-person male protagonist as the main perspective, weakening the proportion of the main plot, and adding details of getting along. The main focus of this book is love cookies, and it will be updated simultaneously with the previous book. As the only heir to a traditional Japanese dance family, Naghiko Fujisaki was asked to learn the postures of girls and live with a new identity in order to better practice dance. His progress was not ideal at first, and the world turned upside down, but he could not find a reason, and his whole life became chaotic. He didn't have time to climb the tallest tree to catch the last cicada, but the courtyard next door, which had not been occupied for a long time, welcomed back its owner in autumn. The little granddaughter of that family is a little lady wearing a pink princess dress and a diamond crown. She is wrapped in complicated and stacked lace, like an exquisite porcelain doll. Nagihiko decided to use her as his first learning sample. He began to observe her, starting from the second meeting when she reluctantly but obediently called him brother. He watched her sing in the forest like a passing lark, watched her jump rubber bands and pass flower drums with the girls, watched her climb over walls and climb trees to pick kites for others, watched her help her friends fight with naughty boys... Oops, this person didn't seem to meet the world's definition of a girl, but it was too late. Nagihiko found that he had long been accustomed to looking at her in various positions.
