On the July 31 airing of JTBC's 'Man of Great Strength,' Sunny had an angry outburst at the crew's accusations that she smokes.

When all eyes were drawn to the little bag Sunny was holding, Kang Ho Dongsuddenly burst out laughing. Eun Ji Won commented slyly, "Are you thinking of what I'm thinking?" Kang Ho Dong replied, "Well, if this was 'A Hyung I Know,' then I'd just say it..." trailing off.

The members were referring to Sunny's past appearance on 'A Hyung I Know,' during which Heechul had accused her of smoking 'Menthols.' Realizing that the members were laughing at her, Sunny yelled in frustration, "I don't smoke! I even said so during my appearance on 'A Hyung I Know.' The term 'Menthols' appeared in the real-time searches next to my name thanks to Heechul!"

Lee Kyu Hwan proceeded to take Sunny's hand and sniff it, saying, "It's not Menthols." He then joked, "They just smell like regular cigarettes."
