In the FC Mobile semifinals held at the Busan Esports Arena on the 28th, Kwon Min-seok (Gyeongnam) and Yu Chang-ho (Jeonnam) successfully secured their spots in the finals.

The first semifinal match featured Gwangju's Kim Tae-hyun against Gyeongnam's Kwon Min-seok. Kim took an early lead by scoring two quick goals, but Kwon fought back with aggressive play in the second half to level the score at 2-2. Ultimately, however, Kim Tae-hyun clinched a 3-2 victory with a last-minute goal from Vinícius Júnior.

In the second set, Kim Tae-hyun again drew first blood, but Kwon Min-seok equalized before halftime, ending the first half at 1-1. Kim had a scoring opportunity with Klose, but failed to convert, and with neither side scoring in the second half, the match went to extra time. In extra time, Kwon Min-seok scored with a Dembélé Finesse Shot to win 2-1, leveling the set score at 1-1.

The final third set was as tense as the previous matches. Both players traded a goal in the first half, and just before the end of the second half, Kwon Min-seok scored his second goal to secure his place in the finals.

In the second semifinal match, Daejeon's Jang Jae-hyuk took an early lead, but Jeonnam's Yu Chang-ho quickly equalized and added another goal in the second half to turn the game around 2-1. As the one-goal lead held steady, Yu scored a clincher in the 83rd minute to make it 3-1. Although Jang Jae-hyuk managed to pull one back to make it 2-3, time ran out, and Yu Chang-ho took the first set 3-2.

In the second set, Yu Chang-ho scored first in the 36th minute with a quick-tempo shot from Son Heung-min. Jang Jae-hyuk found a good opportunity in the 45th minute, and although his initial shot with Bellingham was blocked by the goalkeeper, he finished the rebound with Ronaldo to tie the game at 1-1. In the second half, Yu scored again, and Jang immediately equalized to make it 2-2, but Yu struck once more with Son Heung-min just before the final whistle to defeat Jang 3-2 and advance to the finals.
