Jessi and Jackson slayed their performance of Jessi’s NUNU NANA at the KBS Song Festival, but what gained the attention of fans was Jackson’s amazing manners toward Jessi.

Following the usual rendition of Jessi’s hit song, GOT7‘s Jackson joined her on stage with his on-point rap and dancing.

But what fans noticed was the fact that Jackson’s hand was stiff and staying off of Jessi’s chest area when he put his arms around her shoulder.

Fans are calling these manner hands and praising Jackson for his respect for Jessi.

Not only that, but fans also noticed how he kept his eyes closed when he stood face-to-face with Jessi up close.

Seeing from his overall behavior, it’s predicted that this was all out of consideration for his “sunbae”, Jessi.

Even while making sure to be a gentleman, Jackson totally slayed the performance with Jessi, and fans are demanding that they do a formal collaboration.
