Only Heechul can call Jessica that...

Super Junior Kim Heechul and Girl's Generation Jessica Jung. These are my theory...

For the first time I making this theory that Heesica is real and relationship between Kim Heechul and Jessica Jung are way deeper than just brother and sister. Important : This is just theory. I do not want cause chaos or misunderstanding from this.


There are many nicknames for Jessica like Ice Princess.


Jessica is the type of girl that does not care about what people think about her. She always keep her anger or secret from reveal. But sometimes she can tell her feelings to her only trust oppa, Kim Heechul. Kim Heechul can understand Jessica feelings and he helped her.


A nickname that rarely and most hate nickname to be called is Sickkal (knife). She hate if anyone called her by that nickname. The weird thing is that Jessica do not like other called her by that nickname except Heechul.


Prove:
Sica doesn’t like if someone call her with Sickkal (knife) except Heechul “Jessica said ‘good luck’ to us, even if it’s also her group’s comeback stage!” –2PM
