Rookie boy group CORTIS is facing mounting criticism after comments made during a livestream following the opening concert of their first world tour sparked a heated debate among Korean netizens.

The controversy comes after the group’s debut concert had already received mixed reactions from fans. While supporters praised CORTIS for their energy on stage, many attendees criticized the show for lasting only about 1 hour and 40 minutes, featuring repeated songs in the setlist, and offering few costume changes or special stage performances.

Some fans defended the group, arguing that CORTIS simply does not yet have a large enough discography to perform a much longer concert. Others, however, felt the production did not justify the ticket price.

Instead of easing the criticism, a livestream held after the concert added even more fuel to the debate.

During the broadcast, member Martin reflected on the atmosphere inside the venue and admitted he felt disappointed by the audience’s reaction.

“When we give everything we have on stage but don’t feel like people are enjoying it through their support or cheering, we honestly feel… a little sad.”

Although the comment appeared to express the group’s emotions after their first major concert, many Korean netizens interpreted it very differently.

The clip quickly spread across online communities, where critics argued that the members were focusing on the wrong issue.

A viral post claimed that idols are the ones being paid to entertain fans—not the other way around—and that concertgoers spend both time and money expecting a memorable performance.

According to the post, artists have a responsibility to deliver a show that satisfies the audience before expressing disappointment over the crowd’s response.

Many comments echoed that sentiment.

“They became complacent far too early,” one netizen wrote. “Before saying you’re disappointed, make sure you’re giving people what they paid for.”

Another compared the situation to customer service, arguing that if a restaurant serves poor food, customers have every right to complain rather than being blamed for not enjoying the meal.

Others felt the livestream gave the impression that CORTIS was placing responsibility on the audience instead of acknowledging the concerns fans had already raised about the concert itself.

Some also criticized the timing of the broadcast, saying the group should have addressed other issues—such as complaints surrounding their delayed airport appearance—instead of discussing the audience’s enthusiasm.

Several commenters argued that, as a rookie group, CORTIS should still be focused on proving themselves through their performances rather than expecting unwavering praise from fans.

Despite the backlash, other fans defended Martin’s remarks, saying his comments reflected disappointment rather than criticism and that performers naturally hope to receive energy from the crowd during live shows.

Nevertheless, the livestream has intensified discussion surrounding CORTIS’ first world tour, with many fans now calling on the group and its management to better address concerns about the concert experience while being more careful with public messaging.

For now, what was intended as a heartfelt reflection after an emotional first concert has instead become one of the biggest controversies surrounding the group’s young career.
