Searching for a story

im looking for a bl manga about a boy who read a book about a princess when he was little and now he is looking for a prince. Timeskip to high school. He and his childhood best friend are at the same school where the boy see the student council president and decide that is his prince and decides to spend time with him. Childhood best friend which includes pretty sure is the main character says that the student president is bad and he actually was. Some stuff happen which I don’t remember but the childhood best friend gets sad the boys sister come and talks about their childhood and the boy found his prince which was the childhood best friend. Sorry if this was confusing.
