[talk] Ice water shampoo sounds so cold!

Cha Eun-woo wanted to wash his hair, but he hesitated because the water in the place they were staying was groundwater that was colder than cold water.

He said to Lee Je-hoon, "Hyung, I want to wash my hair, but if I wash it with this, will it freeze?" Lee Je-hoon replied, "Your hair might freeze and break. But if it's really itchy, it's worth a try."

So, Cha Eun-woo ended up washing his hair with cold groundwater. While doing so, he would hypnotize himself by saying, "Ah, it's warm. Ah, it's hot. It's summer," and laugh, saying, "My head is gradually losing its feeling."
