Actress Ha Ji-won showcased her signature variety show charm as she competed in a slang battle with Ryu Seung-ryong and Kim Si-ah on the YouTube web entertainment program 'Class of '26, Ji-won Here.' On the episode released on the 20th, Ha Ji-won, Ryu Seung-ryong, and Kim Si-ah, who all star together in the film 'Bigwang,' appeared as guests. Set in the 'Class of '26 universe,' the three immersed themselves in an improvised skit. Ha Ji-won and Kim Si-ah played new students, while Ryu Seung-ryong took on the role of a returning senior, delivering natural comedic performances. In particular, Ha Ji-won and Ryu Seung-ryong competed to guess the meanings of slang terms presented by Kim Si-ah, such as 'ijikkakka,' 'nagatgyeong,' and 'seolcham.' The scene where the teenage Kim Si-ah explained the slang terms, effectively tutoring Ha Ji-won, drew laughter. Ha Ji-won called Ryu Seung-ryong 'eukkkeuk' (old-timer) and repeatedly shouted 'yar~,' a phrase she learned on 'Class of '26, Ji-won Here.' Ha Ji-won then recreated 'Text message, song!' a famous catchphrase from the drama 'Secret Garden,' and Ryu Seung-ryong responded cheerfully, highlighting the chemistry among the cast. When Ha Ji-won asked Ryu Seung-ryong, 'Did you appear as a frog in 'Bigwang'?' he improvised a frog impression on the spot, adding more laughter. Additionally, Ha Ji-won personally participated in filming a Reels 'acting challenge' to promote the film 'Bigwang,' rolling up her sleeves for the promotional effort. Ha Ji-won previously enrolled at Kyung Hee University and has been appearing on 'Class of '26, Ji-won Here,' where she communicates with Gen-Z university students, continuing to take on various challenges. Meanwhile, the film 'Bigwang' is scheduled for release on September 2.
