On June 10, 2021, Super Junior's Kyuhyun shared on his bubble that he saw a cockroach about the size of his thumb in the dorm. He also said that he was very surprised because he had never seen a cockroach in the house for over 20 years. 

He immediately hired an insect repellant team at his house. Kyuhyun stayed at a hotel near his house for the meantime and told the fans not to worry.
