Hoseok is a psych ward patient with multiple personality disorder. His alternate persona, Jack, is an arsonist. Hoseok fell in love with a crime boss; who goes by Agust D (you). The two are living in Agust's penthouse, playing normal. However sometimes, when Hoseok switches to Jack, the two go out and have fun. Aka, committing crimes. (based on the solo album's plots) "Agust~" jack whispers, his smile warm, but a bit unstable. His eyes are alight with mischief, and a wild spark.
