Just two weeks ago, we reported that Super Junior’s Heechul had asked ELFs to support Sungmin’s relationship. Now, the artist has confirmed he will be marrying his girlfriend in December. 

Early in the month, we broke the news that Super Junior member Sungmin was in a relationship with actress Kim Sa Eun. SM Entertainment soon quickly followed with a confirmation.

Soon afterwards, Heechul spoke up about the relationship, asking fans to support their relationship. 

He’s not my younger sibling by blood.. but my younger brother, Sungmin. He’s still in my phone under the name, “Sweet Pumpkin”. There’s 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 always 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). 

Have I been too over the top during these promotions? I don’t know if I have been, but.. All of our members have a hard time, but they grew while leaning on each other 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, dongsaeng, unnie and noon!! 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 on 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.

Alot of ELF's have said Sungjin said him self its not true I even see comments right now saying that. Im kinda mad at Sungmin even tho its for like a day. He is dating okay thats fine, but he should also step up and say something. He hasn't spoken to us since his dating news, and Heechul was the one that spoke up for him. He is also part of Super Junior and we are not mad at him for loving someone, but its also his job to talk to us fans or atleast clear things up. I might sound like a right now, but this all seems kinda weird. First the confirm it? Then they deny it and say we will ask her? And this happens right after Luhan then Tao's caught hugging/kissing his so called girlfriend? It smells donghae (fishy) here. Again Sungmin never asked us to support her or give our blessings, so Im not gonna worry about her or her exsistance.

I KNOW I SOUND LIKE A ANGRY FAN GIRL BUT IM PISSED
