Min Sa-Oak is seen during the meeting of Shi-Woon Yi for the first time, he was the one of the elders who was shown the most pleased. When the other elders appeared to be checking whether they could accept Shi-Woon as head, he already seemed to have accepted Shi-Woon. 
Into the Depths of the Sun-Woo Clan's Hellish Training, Shi-Woon!!Edit
Right before meeting him the second time, he stated that secretly guarding Shi-Woon might be misunderstood as imprisoning him. He then went along with Elder Kwon's suggestion to leave it up to Shi-Woon, whether to secretly guard him or not.
After officially recognizing Shi-Woon as new head of the clan he shows interest in Shi-Woon's ability to use Ki despite his shattered Ki-center. Still he is pleased to see Shi-Woon cope good with his duties and does not dig deep into the matter.
He and members of Sun-Woo Clan along with Sera Kang travel by helicopter to rescue Shi-Woon. When Sun-Woo Clan arrives he says that he thought the government would be flustered by their arrival, but instead they are prepared for them like bring a military helicopter to intimidate the Sun-Woo Clan. He sees the helicopter hovering over an area with the search light on and notes a match is going on. He is shocked to see the Ganju and Ju Sang-Sik are fighting, then to his shock Elder Kwon leaps out of the helicopter and he says it’s too high to jump.
As Jin-Ie jumps out of the Helicopter, Min along with Kim Sul-Joong follow her to stop her from falling. When they arrive on the ground, Min claims it's chance for a rare workout. As Min and Kim then prepare to fight the Murim Special Ops, they are then greeted by the Sun-Woo Clan members, and allow them to take care of things.
