After premiering in last place among its more high-profile competitors The King 2 Hearts and Rooftop Prince, the viewership ratings for Man from the Equator steadily climbed due in large part to Uhm Tae-woong's praise-worthy acting and the well-combined plot of romance, fate, revenge and success.

[8][9][10][11][12] One the driven top student and the other a happy-go-lucky troublemaker, Jang-il (Siwan) and Sun-woo (Lee Hyun-woo) become unlikely buddies in high school, both poor but proud in their own ways.

Jang-il (Lee Joon-hyuk) has become a prosecutor haunted by his past, while Sun-woo (Uhm Tae-woong), the young CEO of investment trust company Royal Tree, is plotting his revenge.

Their fates are intertwined with the women they love—Ji-won (Lee Bo-young), a volunteer reader for visually impaired people who now works as a VIP party planner at a five-star hotel, and Soo-mi (Im Jung-eun), a hyper-realism painter.

As Jang-il and Sun-woo vow to destroy each other, the truth unravels in a harrowing cycle of deception and revenge as the crimes and secrets of yesteryear come to light.
