Please Look at Me. (Harry Potter's Character Change, Lord Siha)

This story is set in the Order of the Phoenix. Snape teaches young Harry Occlumency, but in the process, young Harry inadvertently invades Snape's memory and sees his father's bullying of the professor in the past, thus re-examining his father and professor. I have to admire the original novel's description of little Harry's conflicting mood very well. Unfortunately, in order to express the plot more completely, the movie briefly mentions little Harry's mood. Those who are interested can read the original work.
