Jang Dong-yoon, Seol In-ah, and chu yeong-woo. On April 23, KBS 2TV Wall Street drama ⁇ Oasis ⁇ (director Han Hee / playwright Jung Hyung-soo) released the behind-the-scenes footage of the main characters who led the ⁇ Oasis ⁇ such as actor Jang Dong-yoon, Seol In-ah and chu yeong-woo. In the last broadcast, Lee Doo-hak (Jang Dong-yoon) and Hiroo Shin (Seol In-ah) learned the truth of what the family of chu yeong-woo had done and vowed to take revenge on them. At the end of the reason why Duhak entered the prison with a murder charge instead of Cheol-woong and the reason why Duhak's father, Lee Jung-ho (Kim Myung-soo), suddenly died, there were Hwang Chung-sung (Jeon No-min), Kang Yeo-jin (Kang Kyung-heon), and their hound Oh Man-ok (Jin-han). Duhak, who can't stop revenge because of his rage, Mind, who wants to protect him until the end, and Cheol-woong, who revealed all his bare face. Again, the flames of the three mixed youths burned hot. Among them, the photos show Jang Dong-yoon, Seol In-ah, and chu yeong-woo's passionate shooting scene. In a scene where a lot of opinions are shared to raise the emotions of a scene character, the efforts of the actors to fully immerse themselves in the character as well as the eyes, facial expressions and gestures are conveyed. Jang Dong-yoon is leading the center of the drama, expressing the complex emotions of Duhak in three dimensions. From the sad eyes toward my beloved lover Mind to the tough charisma that never bends toward revenge, I captivated the hearts of viewers with the constantly agonizing science itself. Seol In-ah is gaining a favorable response from viewers as the most reliable support in ⁇ Oasis ⁇ . As a representative of the film industry in the youth age, there is a lot of cheering for Mind's willingness to take risks for the sake of making Faith's own way and loving Duhak, adding to the bright and dignified energy of Seol In-ah. The presence of chu yong-woo, which shines as the times go by, attracts attention. The appearance of Chulwoong, which is confused and confused among all characters such as Duhak, Mind, Loyalty, Aftershock, and Manok, is like a time bomb. The screaming cry of Cheol-woong, who had been exposed to the truth that he wanted to hide so much, raised the tension of ⁇ Oasis ⁇ .
