Recently, AKMU fans wonder if Changhyuk's Instagram has been hacked after his latest post on April 5th.

On this day, Chanhyuk posted two photos in which he posed in the warm spring weather with his sister and fellow AKMU member Suhyun. Chanhyuk is often seen posing in photos with his sister as he has been promoting with her for a few years. However, many fans know that these two artists show true sibling chemistry as he was seen unfollowing Suhyun on social media, never giving each other compliments, and seen not speaking a word to each other in the waiting room. 

However, Chanhyuk made fans speculate that his account has been hacked because of the positive caption he included in the Instagram post. Chanhyuk wrote, "With my beloved Suhyun," expressing an unexpected fondness for his sister.

Fans commented on the Instagram post, saying, "Is this...hacked?" "Beloved...??" "What's going on?" "Chanhyuk, are you sick somewhere?" "Beloved?!?!? Did Chanhyuk change?" "If you're being threatened, let us know by shaking a carrot LOL, (beloved...?)" "Did Suhyun write this?" and "Was your Instagram hacked?" At the same time, other netizens commented in an online community saying, "I think he changed after his military service," "My brother once lost his mind for a brief moment and was so fond of me lol, maybe it's like that," "Aww they're so cute," "I think he feels much love since he returned from the national service but then he'll return to normal soon," and "His account is definitely hacked."
