School idol dramas based on manga or novels were very common. These works would usually be adapted based on the original story background and character settings, and some additional plots and characters would be added to create a new story. Some school idol dramas would even adapt the fighting elements from the original works into more romantic plots. For example, Detective Conan would be adapted into a romance drama such as Detective Conan: The Scar of First Love.
To be honest, I don't know of any particular comic that has Amy Klobuchar as a character. Maybe it's a niche or rare comic that hasn't gained widespread attention.
The kiss of Amy Chu in the comic could be a symbol of love, a moment of confusion, or a key event that drives the story forward. We'd need to read the comic to know for sure what it means and how it impacts the story.
As someone who loves to read novels, I don't have any news about the manga being updated in real time. I suggest you check the relevant comic website or social media account for the latest news.
