Lars Veldwijk struck a last-gasp winner as Jeonbuk Motors survived a scare at K League 1 new boys Busan lPark in a 2-1 win.
In just the second weekend of action as South Korea's domestic season returned amid the coronavirus pandemic it looked as though Jeonbuk was heading for a frustrating draw on Saturday.
But substitute Veldwijk outmuscled Yun Suk-young, whose slack defending was punished with a drilled, close-range finish from Han Kyo-won's cross in injury time.
In a frantic match, Hong Jeong-ho's glancing header from Son Jun-ho's free-kick had Jeonbuk in front and Cho Kyu-sung hit the post with the goal gaping, which would have doubled its lead before the break.
Busan was handed a lifeline in the second half when Lee Dong-jun was tripped by Kim Jin-su inside the box. It was difficult to decipher from television replays whether the full-back got a touch on the ball but referee Kim Hee-gon decided to stick with his original decision after a VAR check.
Romulo coolly rolled in the leveller from the penalty spot before Kim Byung-oh had a moment of woe when he missed a sitter shortly after as Busan found some momentum.
And Jeonbuk made it two wins from two to start its campaign thanks to Veldwijk's late intervention.
Daegu fell behind before earning a 1-1 draw at home to Pohang Steelers.
Aleksandar Palocevic timed his run well to slot home Song Min-kyu's cutback shortly before half-time for his second goal in as many weeks.
But Edgar Silva's powerful header midway through the second half earned a share of the spoils.
Sangju Sangmu is up and running for the campaign after a 2-0 triumph over Gangwon.
Kang Sang-woo's 22nd-minute penalty had the home side in front and Moon Seon-min's goal on the counter 12 minutes from time saw Sangmu make amends for a 4-0 loss at Ulsan last weekend.
