SHINee's Taemin said he wants Key to make a big mistake. 

 
On the June 13th installment of 'Weekly Idol', SHINee featured as guests with their 10th anniversary since their debut. During the profile segment, Taemin wrote of himself, "My positive is that I'm kind," and "My negative is that I have an awful temper." He explained, "I have no middle ground. I have a hot temper, so I get angry really quickly and apologize."

As for Taemin's drawing of his own brain, the MCs noticed he included, "To block Key's future," and "Annoy Key." He revealed, "Key hyung always annoys me and makes me cry. I hope hyung makes a big mistake on broadcast. He's too good at MCing and everything. Even monkeys fall from trees though, so I hope that happens to make him miserable," making everyone laugh.
