BLACKPINK's Jennie's Cute Habit Is Something She Does Only When She's With Jisoo - And It Shows How Close Their Sisterly Bond Is

Upon first look at BLACKPINK‘s Jennie and Jisoo…

…you may mistakenly think that Jennie is the older of the duo because of her “intimidating presence” and high-class visuals…

…and because Jisoo looks a bit brighter and younger with her ever-smiling face and goofy smiles.

That’s why it’s a little surprising to know that Jisoo is actually the oldest member in the group.

Upon closer inspection, though, when you finally take the time to check out the interactions between the two…

…you would realize that Jennie actually treats Jisoo as her “older sister” by the way she adapted to Jisoo’s habit of poking her on the side to get her attention.

Now, while Jennie and Jisoo’s poking habit is too cute for words…

…Jennie’s adorable habit that she does whenever she’s with Jisoo is actually about her comfortably and playfully hitting her unnie every time Jisoo makes her laugh.

In fact, Jennie does this every time Jisoo does something funny — this just shows how close they are to each other, since skinship is done in a comfortable, but still respectful manner.

Keep on making each other laugh, girls!

The bond between these two fantastic girls is definitely sibling-like — perhaps this is why Jennie felt comfortable enough to gently “slap Jisoo’s hand” in an effort to protect their brand’s image as official ambassadors:
