Following the news that Super Junior's Sungmin was in a relationship with musical actress, Kim Sa Eun, Heechul posted a thoughtful Instagram post, showing his affections towards his fellow group mate.
He wrote, "He's not my younger sibling by blood, but.. my younger brother, Sung Min. He is still in my phone under the name 'Sweet Pumpkin.' There were lines like, 'Cook a lot of sweet pumpkins ~ because I stuffed myself with it all ^-^".. I had forgotten kekekeke Sungmin, who is always quiet and never causes trouble, was especially busy today.. ^-^ There is something I constantly say: 'Hey, you can't hit Sungmin, even with a flower.' That's right. You can't hit Sungmin with a flower or even with my face (It's a flower. Of course, of course) keke. Have I been too over the top during these promotions? I don't know if I had been, but.. All of our members have a hard time, but they grew while leaning on another and enjoying it. They will in the future, too. That's why let's all hold hands and get along for a long time like oppa, dongsaneg, unnie, noona!! I hate cheesy words the most, but our Sungmin.. the Sungmin who never cried.. said, 'Hyung.. I'm sorry.. to the fans, too.. to the members, too..,' which upset me, so I'm like this.. The path Sweet Pumpkin is going might not be the Silk Road, but let's not make it a thorny path~ I love you, my children!! Although I'm the Heechul, who can't make a proper heart TT bbuing bbuing."
