Oppa posted a BTS video of the last shooting day of "The Heirs." In the video, our prince happily approached and hugged almost everyone in the set. He posted the video with this caption: "4개월 동안 김탄으로 행복했습니다. 여러분도 '상속자들'을 통해서 많은 용기를 얻었기를 바라며, 직진! For four months, Kim was happy with the shot. You, too, ' the heirs ' got a lot of courage through hope, straight!"
