On August 24, an all-kt Rolster showdown took place between 'UTA' Lee Ji-hwan and 'Dike' Kang Mu-jin in Round 3 of the 2026 FSL Summer Final Stage at Jamsil DN Colosseum. As a result, KT's 'UTA' Lee Ji-hwan defeated his teammate 'Dike' Kang Mu-jin 3-2 after a hard-fought full-set match.

In Set 1, 'Dike' Kang Mu-jin scored the opening goal, but 'UTA' Lee Ji-hwan immediately equalized in the 17th minute with a powerful strike from Essien. However, that was just the beginning. 'UTA' pressed even harder in the first half to take a 3-1 lead. 'Dike' did not back down easily either, scoring two goals in the second half to push the match into extra time. Ultimately, in the all-important extra time, 'UTA' found the back of the net to seal a 5-3 victory.

In Set 2, goals did not come easily. Neither player could break through the opponent's defense, turning it into a single-goal battle, with no goals scored throughout the first half or up to the 81st minute of the second half. Then, 'UTA' scored the opening goal with Gerrard on a counterattack in the 80th minute, but 'Dike' soon equalized to make it 1-1. Unable to break the deadlock even in extra time, the two went to a penalty shootout, where 'Dike' claimed victory after making a save.

Then in Set 3, 'UTA' reclaimed the momentum by defeating 'Dike' by a large scoreline of 6-2. In the following Set 4, goals poured in from the first half. As the 40th minute of the first half passed with 'UTA' leading 2-1, 'Dike' gave chase to make it 2-2. However, right before the end of the first half, 'UTA' broke through the defense with Eto'o to add another goal, closing the first half with a 3-2 lead. Although 'UTA' held a one-goal advantage, 'Dike's attacks remained sharp. Finally, 'Dike' equalized 3-3 in the 75th minute.

Once again, the match went into extra time. Even in that brief stretch of extra time, both players exchanged a goal each; 'UTA' scored again to make it 5-4, but 'Dike' caught up once more and won in the penalty shootout, tying the set score at 2-2.

In the final Set 5, 'UTA' opened the scoring with Suker in the 26th minute. He then added another goal in first-half stoppage time to end the first half 2-0. Holding a two-goal lead, 'UTA' played with composure. Desperate for a goal, 'Dike' made it 1-2 in the 70th minute with a quick-release shot by Totti, and shifted the momentum in his favor by bringing it to a 2-2 tie in the 77th minute. The game headed into extra time once more, and 'UTA' added a goal to take a 3-2 lead. However, while defending well, 'UTA' carelessly conceded possession, bringing the game back to a 3-3 deadlock. In the penalty shootout that would decide the winner between the two, 'UTA' secured his first shootout victory this time, emerging victorious after a lengthy battle.
