This article is a SJ+TVXQ fanfic. If you don't like it, please don't read it. Thank you ~ I am addicted to Harry Potter recently, so I made this willful work. Because it is the Asian branch of the Academy of Magic, except for the different characters, everything else is modeled after the setting in Harry Potter. It is borrowed from the setting of Harry Potter. I think the world setting of the novel is very powerful and I admire it very much. Of course, there is no Voldemort here. Please don't care about age, because college is destined to have teacher-student love, student love, and teacher love. This article has been filled with holes and will not be filled in.
