L.J. engineers for Tae Ik and Kang Hwi to compete against each other on a new reality show called “We Are Rivals.” Tae Ik and L.J. make a wager that if Tae Ik wins, he gets Full House (his old family home), but if he loses, he’ll return to U Entertainment and work for L.J. again. Meanwhile, Man Ok’s grandfather discovers that she is working as a stylist for Kang Hwi and goes to confront her. When she refuses to return home with him, he tells her to never return to the dojo again.
