On October 16, Heechul made his Instagram private and wrote a message, suggesting he would be taking a break temporarily while things settled down after the news of Sungmin's upcoming marriage came out.

However, it appears he is very serious as he does not stop there!  He also went to his Weibo account and wrote, "Let's meet in China.  I will also take a break from writing on Weibo.  Everyone, do not speak again about the things that put you in a bad mood and do not get hurt.  Be happy."

It is not certain this has entirely to do with Sungmin's upcoming marriage, raising curiosity about the exact reason behind his halted SNS activities.  However, he does not leave further information.

Meanwhile, Super Junior will engage in special album promotions next week.
