ZE:A's Siwan did his best impression of the well-known internet meme "grumpy cat."

On the 28th, Siwan tweeted, "Grumpy cat [acting like] a human! Truthfully, it's me who's [acting like] the cat~," along with the photo above.

In the photo, Siwan can be seen mimicking a cat resting atop a stool.

Fans commented, "They do look alike", "Playful Siwan is so lovable", "So cute", and more.

Who do you think is cuter? The cat or Siwan?
