The reason behind the showŌĆÖs popularity lies in its compelling narrative of poor secretary Yoon Hyun Woo (played by Song Joong Ki) being reborn as Jin Do Joon (Song Joong Ki), the youngest son of a super-rich family. Yoon Hyun Woo risked his life to do all the dirty work of the Sunyang Group only to get betrayed and killed by them. However, he miraculously wakes up in the body of their youngest son in the year of 1987. Jin Do Joon, who sees the future of both the country and the Group, makes waves every time he moves with his plans. He vigorously looks for the culprit behind his death and teases the satisfying revenge on its way, leaving many curious about what will happen next. The series won many viewersŌĆÖ hearts as he hid his real ambition until he became an adult to deliver his revenge at the right moment. He used his knowledge and power to read the future of the presidential election and saved his grandfather Jin Yang ChulŌĆÖs (Lee Sung Min) life from a hijacked airplane. He also successfully made significant profits from investing in Bundang real estate, making him the envy of all. Plus, Song Joong Ki, Lee Sung Min and Shin Hyun Bin made the show all the more immersive with their great performance. Source (1)
