Kyungbock High School launched an investigation to find the student who allegedly posted sexual harassment comments about aespa on social media.

On May 4, an official from the Kyungbock High School stated in a phone call with a reporter, "We found the student who posted inappropriate comments about aespa, and the student admitted to his wrongdoing. We're investigating the circumstances in which he created the post." The official added, "After the investigation concludes, we will take measures to suspend the student or give him disciplinary volunteer work."

The official explained that they had found another student who posted inappropriate content online, but the school won't be able to punish the second student because he had already graduated. Kyungbock High School is continuing its investigation to find more students who posted inappropriate content about aespa online.

Meanwhile, aespa was invited to perform at the annual Kyungbock High School event and was reportedly harassed due to poor security. There were social media posts where some students made inappropriate, suggestive comments about the members. One netizen who is speculated to be one of the students at the Kyungbock High School wrote, "I did everything except touch them."

Soon after, Kyungbock Highschool posted an apology but was heavily criticized as the school blameshifted to outsiders who allegedly attended the school event without permission. With growing criticisms against the school, Kyungbock Highschool posted a second apology and launched an investigation against the students who posted inappropriate content online.
