Son ho joon sacrificed himself to leave evidence to prevent further damage. In the SBS Friday-Saturday drama "The police station next to the fire station a," which aired on the 11th, Bong Do-jin (Son ho joon) was found dead. Bong Do-jin proposed to tongue-in-cheek (Gong Seung-yeon), who said, "I'm afraid of going into the fire these days. "I'm afraid of that," he confessed to tongue-in-cheek. "Why do you make such a strange sound?" tongue-in-cheek said, "Do not cry too much." However, this was not the case: Bong Do-jin was discovered as a cold corpse, while Qin Hao (played by Kim Rae-won), his family at the fire station, and his younger sister Bong Anna (played by Ji-woo) all sobbed. A fellow firefighter said, "I went in alone when I heard that there was a child (Bong Do-jin) who couldn't come inside." After Bong Do-jin's Death, the Qin Hao dog began to dig into the incident with venom. "There's something you need to see." Bong Anna brought Bong Do-jin's oxygen respirator. I wonder why he took off the air breathing machine. "Baek Cham (Seo Hyun-chul) also questioned," Who else was there other than Dojin? "Even testimony came out that" Dojin said he saw a star-shaped flame in the material warehouse. " Qin Hao had the possibility of being killed, saying, "It is unlikely to be a simple accident." Bong Do-jin's autopsy was carried out under Qin Hao's view. "The eyeballs were gone," said yoon hong (played by Son Ji-yoon), who performed the autopsy himself. From the esophagus to the stomach were filled with white crystals from the Grammy Award for Best Rap Performance. After everyone left, yoon hong said, "I'm sorry I cut your body." tongue-in-cheek, conscious, also sobbed at the belated news. Upon his return, tongue-in-cheek arranged Bong Do-jin's locker alone, which contained a note Bong Do-jin had written to his family and tongue-in-cheek. In the letter, Bongdojin said, "If the day comes when I can not get out of the fire, so if you read this letter, I will just be relieved by the fact that you were not next to me at that moment." As a result of the autopsy, it was the components that constituted the Candle that flowed into the stomach and esophagus of the bongojin just before Death. Matthew (Lee Do-yeop) took a break for a while and fell down after taking a drug that caused cardiac arrest for 30 minutes. Qin Hao identified Dok Go-soon (played by Woo Mi-hwa) as the key suspect in The Texas Chainsaw Massacre: The Beginning arson attack. tongue-in-cheek, yoon hong, and bong Anna decided to reconstruct the fire by making Candle with Candle ingredients. As a result of each fire with the manufactured Candle, the high-temperature paraffin Candle exploded with Jeriken. tongue-in-cheek said, "If you were Dojin, you would have known it as soon as you saw it." Bongdojin had already predicted the explosion. Bongdojin had eaten Candle to get evidence before everything disappeared. The Texas Chainsaw Massacre: The Beginning arsonist delayed the fire with a Candle, causing a simultaneous fire. The tongue-in-cheek "was neither a murder nor an accident. The sacrifice of a firefighter to save everyone. That is the truth of this Death. " With the evidence gathered, Qin Hao identified only Yang Shuang as The Texas Chainsaw Massacre: The Beginning arsonist. Then Yang Shuang confronted tongue-in-cheek in front of Bong Do-jin's house and attacked him with a hammer.
