Jaejoong shared, "My character Jang Dong Chul (Heo Young Dahl) is a man who has lived persistently like a weed to survive since he was little... Although he is not living an honest life, he never gives up on his hopes and dreams... He is a character who I anticipate to change... I am also looking forward to it since I get to work with good actors and staff through 'Triangle'."
