Ji Chang-Wook joins the cast of JBTC's "Knowing Bros," showing his charms as he plays, dances, and performs acrobatics on the show.

Together with his co-stars Kim Min-Seok and Ryu Kyung-Soo, the trio introduced themselves as the transfer students from the "Lovestruck in the City" High. As they sat in front, Kim Hee-Chul called them out for sitting before introducing themselves. The trio immediately stood up, drawing laughter from the audience.

"Hello, I'm here to heat this frozen winter kingdom," Ji introduced himself, before singing "I'm the handsome Ji Chang Wook," to the tune of Frozen's "Let It Go." Kim Min-Seok and Ryu Kyung-Soo followed suit.

Kang Ho-dong then spiced up the show by jokingly freaking out and asking Chang-Wook to "get out," fearing that "if doppelgangers (a duplicate, look-alike of a person) meet, one of them ends up dying."

Ji Chang-Wook wittingly replies: "I'm not sure how we resemble one another, but it makes me want to die," sending the classroom into an uproar. He then adds that Ho-Dong, like him, is "really cute." The "Healer" star then performed an unbelievably cute aegyo aimed towards the "Knowing Bros" host before turning his back in embarrassment.

In a later segment, the "Knowing Bros" showed a clip of Eum Moon-Suk doing Capoeira-like movements in the 2019 film "Fiery Priest," followed by a video of Chang-Wook imitating him. While everyone was having fun with the actor's long hair and dance moves, they were soon stunned when he did a backflip, prompting the hosts to challenge him to imitate various challenging and funny moves, including Lee Sang-Min's floor slide - which Ji Chang-Wook perfectly copies.

"Lovestruck in the CIty," the new Korean romance drama, premiered on Kakao TV last December 22 and is set for a Tuesday and Friday timeslot at 5:00 PM KST. It is also set for global distribution through the streaming platform Netflix. In the series, Ji Chang-Wook plays Park Jae-Won, an honest architect who can't forget a "camera thief" he met once in the past. Kim Min-Seok plays Choi Kyung-Joon, an architect like Jae-Won, who works in a construction firm founded by his father and uncle. Lastly, Kyu Kyung-Soo is the novelist Kang Geon in the series.

About Knowing Bros

Also known to fans as "Men on a Mission" and "Ask Us Anything," the JBTC entertainment show first debuted in December 2015. Since its seventeenth episode, the show has adopted a high school premise where the hosts - Kang Ho-Dong, Seo Jang-Hoon, Kin Young-Chul, Lee Soo-Geun, Kim Hee-Chul, Min Kyung-hoon, and Lee Sang-Min - all appear as school students, and their guests are the transfer students.

The show, despite its school setting, has become popular for its use of the Korean informal language, regardless of the hosts and guests' age difference and seniority in the industry - creating a level classroom environment where everyone can freely tease and joke around one another.

While the show in its "Brother School" format introduces a variety of segments, one of its most consistent parts is the Entrance Application segment, where one of the hosts reads and reviews the application forms submitted by the guests, usually including the transfer students' strengths, weaknesses, and talents.
