《紧急求助：我们需要你的关注与支持》钢琴红楼馆的奴隶们

　　There is a fire in the classroom. There were two students in that burning classroom. 　　One died and one was taken to the hospital unconscious. Some say it was suicide and some say it was murder. Detective Eun-seob is staking out while the student is dying before he gets called in on the site. He witnesses the most terrible thing there.
