In 'Dog's Voice', Sungjae discovers he can understand dogs, leading to a series of events involving a gas leak and a murder case.

*This article contains content related to the drama's story. Lee Sungjae heard hints about the true culprit of a murder case. In the new KBS 2TV drama 'Dog's Voice', which started airing in Korea on the 25th, Lee Sungjae (played by Lee Sungjae) is depicted as having become able to understand the words of Sophie, a police dog. In this day's broadcast, Hyunta (Nam Yoons) who met Sungjae at the filming site visited the director and asked, 'Why is Mr. Lee Sungjae at this drama's filming site?' and protested, 'I think I clearly told the director, but I cannot act with Mr. Sungjae. I will withdraw.' Hyunta expressed discomfort, saying, 'His very presence is very awkward.' He had been pointed out for his acting skills during the script reading held before filming. In response, the director visited Sungjae and begged on his knees, asking him to withdraw from the drama, and Sungjae showed his anger. At the filming site, Sungjae felt the urge to urinate and, unable to hold it, relieved himself on the street, which led to a debate about 'urine terror' after being spotted by Hyunta's fans. Sungjae visited the hospital due to frequent urination symptoms and received medication, but he suffered from delusions of being bullied by people due to the controversy. He also made a mistake of leaking urine at a café where he promised to meet with broadcasting officials, ruining the meeting. Ultimately, Sungjae went to recuperate on Geoje Island, where his son's new house is located, and there he met the dog Sophie. He realized he could understand Sophie's words and was doubtful. When he unconsciously responded to Sophie's words, he showed surprise, saying, 'What? Did I just have a conversation with this dog?' Shocked that he could understand a dog's speech, he exclaimed, 'Is it a dog? A ghost?' and ran away. Even on the walking path where he fled, he encountered another dog and asked, 'Can you talk too? Try telling me.' However, he ended up being chased by the dog. After returning home, he met Hong Chowo (former MOMOLAND Yeonwoo), who brought Sophie. Chowo, in a sudden call, said, 'I'm sorry, but please take care of Sophie,' and hurriedly left the scene. Sensing something, Sophie urgently told Sungjae, 'Hey, I smell gas. There's a gas smell coming from that greenhouse. It's dangerous, tell those people to come out. It will be a big problem if it catches fire.' Sungjae told Kim Yeong-gon (played by Kim Yeong-gon), Ye Su-jeong (played by Ye Su-jeong), and Song Ok-soon (played by Song Ok-soon), who were gathering at his house, 'Everyone, get out,' but when they didn't listen, he threw food from the plate to send them out. At that moment, the gas exploded, and a fire broke out in the greenhouse. Sungjae told Sophie, 'Thanks to you, I was able to save people,' and Sophie replied, 'Buy me sundae (Korean sausage) later.' Afterward, hearing that Chowo had gone to the scene of a suspicious death, Sophie said, 'I shouldn't be here,' and headed to the scene. After visiting the scene, Sophie told Sungjae, 'It's frustrating, really. It's not suicide. A woman was murdered. That Mr. K over there witnessed it last night,' pointing to a brown dog. Sungjae approached the detective and said, 'This is not suicide. It's a murder case,' and the detective looked at Sungjae with a suspicious gaze.
