*This article contains content related to the drama's story. Lee Seung-jae has once again succeeded in apprehending the true culprit. The 4th episode of the KBS 2TV Wednesday-Thursday drama 'Dog's Voice,' aired yesterday (3rd) in South Korea, recorded a viewership rating of 3.7% (Nielsen Korea, nationwide standard). Ye Su-jeong (played by Ye Su-jeong) is a fan who asks to turn the drama into a webcomic and gives her previously written script to webcomic artist Park Wae-se (played by Ryu Hae-jun). However, an incident occurs where Park Wae-se is brutally murdered in a manner similar to the content of Ye Su-jeong's script, instantly creating tension in Geoje Island. Lee Seung-jae (played by Lee Seung-jae) finds it suspicious, and passionate officer Hong Cho-won (former MOMOLAND's Youngwoo) also struggles to uncover the truth. At that time, Park Wae-se's ex-girlfriend, Song Myung-ok (played by Lee Yu-jin), who was about to get married, confesses that she is the culprit, hinting at an unexpected development. The broadcast of episode 4 depicted Lee Seung-jae's pursuit to reveal the culprit in earnest, teaming up with Sophie. Song Myung-ok claims she impulsively killed her ex-boyfriend Park Wae-se, who was stalking and harassing her. Subsequently, her fiancé, Hwang Jeong-guk (played by Yong Jae-hyun), also confesses to being the culprit, causing confusion in the investigation. Detective Yuk Dong-gu (played by Tae Han-ho) senses that the true culprit is someone else from their conflicting statements, but the investigation falls into a labyrinth as no decisive evidence is found. Lee Seung-jae hears a testimony from another dog, 'Jin-seung,' through Sophie and learns the location of the murder weapon. Jin-seung, who was wandering near the river by Changmi Bridge, accidentally saw a man throwing an axe into the river. Lee Seung-jae meets Hong Cho-won and secretly hands over clues to assist in the investigation. At this moment, they discover they both have the same peach allergy, revealing that they are actually grandfather and granddaughter, raising expectations for further chemistry. While Song Myung-ok and Hwang Jeong-guk claim they are the culprits, the witness testimonies are completely different. Sophie tells Lee Seung-jae, 'I just heard from Jin-seung that the man who threw the axe that day is taking pictures of a newlywed couple today,' overturning the situation with a decisive remark. Lee Seung-jae meets Hong Cho-won again, suggesting that there might be a third person involved, leading Hong Cho-won to suspect wedding photographer Yang Jin-man (played by Ahn Hyo-no). They investigate Park Wae-se's social media and discover Yang Jin-man's connection, getting closer to apprehending the true culprit. Ultimately, the police, following Hong Cho-won's strong assertion, search the river near Changmi Bridge and find the axe, the murder weapon. Fearing that Yang Jin-man might escape, Lee Seung-jae asks him to take pictures to stall him, and the police quickly chase and arrest him. The 'Senior Avengers,' who were blissfully unaware while taking pictures, realize the seriousness of the situation and contribute to the apprehension of the culprit by subduing Yang Jin-man. Later, it is revealed that Yang Jin-man killed Park Wae-se, who was in a relationship with him, out of misunderstanding that he couldn't forget his ex-girlfriend, and the truth that Song Myung-ok and Hwang Jeong-guk thought each other was the culprit and tried to take the blame. On this day, in addition to solving the case, various episodes allowed glimpses into the relationships between characters. Hong Woo-na (played by Kim Ji-young) was robbed by a scammer, Hwang Bin (played by Seo Ji-seok), and had a brief conversation with fellow victim Kim Se-kyung (played by Lee Soo-kyung). The two women, sharing a commonality with Lee Gi-dong (played by Park Sung-woon), empathized with each other, saying, 'I have no eye for men.' Additionally, Kim Yong-gon (played by Kim Yong-gon), showing symptoms of dementia, completely forgot that a day marked on his calendar as an important anniversary was Lee Seung-jae's birthday, leaving Lee Seung-jae feeling lonely as his colleagues did not pay attention to him. Kim Yong-gon, who was celebrated by colleagues for good news like new drama appearances and advertising shoots, dramatically remembered Lee Seung-jae's birthday at the moment he blew out the candles on the cake and cleverly made him the star of the party. The 'Senior Avengers,' who seemed to prepare a surprise event for Lee Seung-jae, provided laughter to the viewers. 'Dog's Voice' captivated viewers with its gripping story and perfect chemistry between characters. Immediately after the broadcast, viewers reacted enthusiastically, saying, 'The pace is fast, and there are no suffocating elements, it's very interesting,' 'Today's case resolution was thrilling,' 'Heartwarming and funny,' 'A drama that heals in the middle of the most exhausting week,' 'Everyone's acting is top-notch,' and 'The last words, 'a gift from a beloved friend,' were warm.'
