Taehyung was dead , Bangtan and Hyeri was so sad about his dead but Hyeri believe that he's still alive and always be there with them . At the first time , no one believe Hyeri that she saw Taehyung , They thought Hyeri still sad about Tae death and always imagine that Tae is alive but did he really alive ? Where he got the body or just Hyeri can see him ? what about the rest ?
