Yes, he might. Kakashi is a complex character with diverse interests. Given his love for reading in general, it's not a stretch to think he could pick up a romance novel from time to time. He seems like the type who would be open to different genres to expand his knowledge and understanding of various emotions and relationships.
Maybe. If the fanfiction stays true to Kakashi's character in their eyes, they might approve. For example, if it shows his loyalty and skill, they could be okay with it.
I'm not sure if Bakugo reads romance novels. He seems more into action and combat - related stuff, but who knows? Maybe he has a secret soft side for romances.
In the world of Bakugou, his main concerns are his own strength, his rivalry with others, and his path to becoming a top - notch hero. There's no evidence to suggest that he has any inclination towards reading romance novels. His time is likely occupied with studying combat techniques, strategizing for battles, and dealing with his intense emotions related to his goals. While it's not impossible for a character to have hidden interests, based on what we've seen of Bakugou, reading romance novels doesn't seem to be one of them.
In the novels, Kakashi's evolution is a gradual process. Initially, he is a very reserved and mysterious figure. His Sharingan eye and his combat skills are what people first notice about him. But as the story progresses, his relationships, especially with Naruto, Sasuke and Sakura, start to change him. He becomes more of a guiding figure, sharing his wisdom and experiences. He also overcomes his past fears and insecurities, which is shown through his actions and decisions as the story unfolds. This evolution makes him a more well - rounded and beloved character in the Naruto universe.
Kakashi's reaction would be complex. He is a man who has lost many people in his life. But Naruto was special. He would hold Naruto tightly, his hands trembling slightly. He might try to use some of his own chakra to keep Naruto alive a little longer, but deep down he knows it's futile. His face would show a mixture of pain, regret, and love. He would remember all the times he trained Naruto, all the lessons he taught him, and how Naruto had surpassed all expectations.
Kakashi might immediately offer a comforting presence. He could put his hand on Naruto's shoulder and just be there silently, letting Naruto know he's not alone.
