According to fans who recently attended Super Junior's encore concert 'Super Show 7S' back on March 3, member Eunhyuk accidentally spoiled news about Super Junior D&E's 1st domestic solo concert way in advance before the news was supposed to go out!

On March 3, Eunhyuk discussed participating in 'Super Show 7S' through the concert production team. He then revealed that he was currently working on another upcoming concert, for Super Junior's subunit D&E!

However, shortly after spoiling the news during 'Super Show', Eunhyuk wrote on his Instagram, "Concert aftereffects. Severe. #OhBTW #The D&E concert news #Wasn't supposed to be today, it's tomorrow or something #Sorry Sorry #Or is it now tomorrow either #Probably tomorrow #Under Nineteen Performance team #Seventeen BSS #Gong Myung." 

Taking Eunhyuk's word, fans eagerly waited for the official announcement of Super Junior D&E's 1st domestic concert that day... however, there was no announcement to be seen. 

Eunhyuk then took to Instagram to explain himself again, apologizing though hashtags, "#The D&E concert announcement #Isn't tomorrow #It's the 7th #Seriously Sorry Sorry #For today, I'm taking a break so let's talk tomorrow." 

Finally on March 7, SM Entertainment announced Super Junior D&E's 1st domestic solo concert 'The D&E'!

To make up for his accidental blunders, though, Eunhyuk then shared some behind-the-scenes practice videos of his solo track "Illusion".
