So far the story seems cool. It just dont make sense how he come in understanding the language but suddenly cant read it on the test exam? Like if he can know the language off rip but he cant see it in writing. Also probably by the time the story started he already seen many words signs in that same language. Like his dorm for say or even classroom number but as soon as the test comes he don’t understand it? Not to critic everything but him not understanding caused basically everything so I wish it was thought out differently
