Super Junior's Heechul was featured as a guest on OnStyle's "TaeTiSeo" as he talks about his close friendship with Taeyeon on the October 7 broadcast.
Heechul have revealed how he admires Taeyeon and at the same time expressed his worry by saying, "Sometimes, it hurts to see [Taeyeon] try so hard to appear strong. She has such a big load that she carries on her shoulder, but she doesn’t even show it. She quietly takes care of people without telling anyone, which is honestly very admirable."
"I’m always thankful [for Taeyeon] because even when I’m going through a really tough time, Taeyeon would comfort me by saying, ‘Oppa, you’re doing well. The problem is those around you.’" Heechul went on, "She told me that she would sing the congratulatory song when I get married."
Taeyeon made a reply to Heechul's statement and expressed her gratitude towards Heechul, "Other than the members, I don’t have many close friends that I have a deep relationship with. But I feel like I get along well with [Heechul] oppa, and he adjusts well to me, so we meet often. That’s why I’m thankful."
Heechul is known to be close to female idols as he expresses his friendship. Idols that are known close to him are f(x)'s Sulli and singer Son Dam Bi, whom has been always rumoured to be his girlfriend.
