AKMU‘s Suhyun just posted multiple photos with her brother, Chanhyuk on her Instagram account for the sole purpose of dissing him.

Suhyun looks absolutely shocked, and what makes the photos even funnier is the fact that Chanhyuk looks serene while sipping his coffee.

The photos were captioned with nothing but a skull emoji, but Suhyun definitely got her meaning across.

So much that Chanhyuk responded with a very brotherly comment.

I’m sick and tired of this.

— Chanhyuk

Meanwhile, Suhyun’s bestie, Kim Sae Ron expressed her disgust.

Ew, what’s wrong with you?

— Sae Ron

There’s obviously no such thing as disharmony between Suhyun and Chanhyuk.

Just absolute hilarity between two typical siblings.
