At the beginning of sixth grade, the first period coincidentally was the Potions class. What was even more coincidental was that the new Potions Professor Slughorn had something to do and Professor Torsnape took over the class. The Potions accident not only gave Harry a day's worth of cat ears, but also a Potions textbook that could travel through time and space... And in the silent night, Harry also met a teenage version of the old bat... The dream was too beautiful, and the edges were blurred with reality, but all experiences were real, especially for a certain Defense Against the Dark Arts professor...
Everyone survived (except Lily James) including Sirius and Cedric. This article is humorous and sweet. Don't be awkward and often catch Harry's sect × wonder why he is always caught. Harry - another version - repeatedly hinted at the tsundere Prince × who wants to redeem Prince.
Warning: The sub-CPs are only for Zhan Li, Rohe, and Draco. There are single arrows, friendship and love. Sirius prefers friendship/family affection to Harry. The main text is about enemies pulling each other to the extreme, without having children.
Intention: some sshp I want to see
