The Supreme King, cold-hearted, ruthless regressor, Yoo Joonghyuk turns into an 8 years old kid after drinking a wrong potion.

W- what's happening??!! M- Mama?? P- Papa?? Anybody?? U- uhh... Uwaahh...

Joonghyuk starts to cry like a kid. He seems like mentally unstable. He didn't understand about what's happening.

Joonghyuk seems confused as well as he shrunk. His mind before doesn't seem like he is now. He's completely turned into a kid. A kid that has a traumatizing childhood.
