Definitely not. Spanking is a form of physical punishment that can be harmful both physically and mentally. Bad grades can be due to many reasons, and a father should support and encourage his daughter to do better instead of using violence.
One possible consequence is that the daughter may become fearful and stressed. This can have a negative impact on her mental health and self - esteem. She might also start to resent her father and their relationship could be damaged. Another consequence could be that she becomes overly focused on grades out of fear rather than a genuine love for learning.
In Fragrant Honey, the father Runyu was a very important character. He was not only a ruthless man with a strong desire for power, but also a controversial figure.
The audience's condemnation of the Father Emperor was mainly because his actions and decisions had caused a lot of dissatisfaction and controversy. For example, he had unfairly harmed his mother and the Heavenly Queen, abused his power, was indifferent to his family members, and even treated his own son unfairly. These actions made the audience feel very angry and disappointed, and thus they had a great disgust for the father.
However, it should be noted that the creation of the Father Emperor's character was also affected by many other factors such as the development of the plot, the character's personality and background, etc. Therefore, the audience's views on the father's scum behavior might vary from person to person and in different situations, there might be different interpretation and understanding.
He might meet the future versions of Naruto and Sakura. Their relationship with him could be very different in the future, perhaps they are now leaders of the village and Sasuke has to adjust to their new status.
I think young Sasuke would have a very intense reaction. He was so consumed by his hatred for Itachi at that young age. A Sasuke vs Itachi fanfiction would be like a trigger for him. He would be eager to see how the fictional fight is portrayed. If Sasuke in the fanfiction is shown as strong, it might fuel his own ego and make him strive even harder to become powerful. However, if the fanfiction shows Itachi as superior, it could enrage him. He might feel that it undermines his own goal of defeating Itachi and he might even want to find the writer to correct their 'wrong' view.
One common theme is Sasuke's struggle to admit his feelings. When he's jealous, it shows that he actually cares more about Sakura than he lets on. Another theme could be misunderstandings. He might misinterpret Sakura's interactions with others as something more than friendship.
In some fanfictions, Naruto might reject Sasuke because of Sasuke's continuous pursuit of power in a way that endangers others. Naruto, who values friendship and the safety of the village, could see this as a betrayal of their shared values.
For Sakura, she could grow in terms of her leadership skills. If they encounter any difficulties in the forest like being chased by a group of wild animals or getting caught in a dangerous situation, she could step up and lead the way out. Sasuke might then realize that Sakura has the potential to be a great leader. And for Sasuke himself, he could become more open to the idea of a relationship with Sakura. The seclusion of the forest could provide the perfect backdrop for him to explore his feelings for her.
Naruto might protect Sasuke by using his physical strength. He's got those powerful jutsus like the Rasengan. If any enemy comes near Sasuke, Naruto can just blast them away with his attacks.
