@MinChuyu i recommend u Mad Hatter, and the second book which is Alice, its a mistery/ thriller/somehow horror bts book and its basically how one of the members was killed and in the first book the police trys to find out who did it. And all the members have some sort of mental illness. TW it left me a bit traumatized, but it's an amazing book
And if u wont be able to find them, i can send them in private to u
