Sunyoul from rookie group UP10TION chose to stay under the blankets rather than frolic in the snow, Wednesday.

It was the second time this winter that it snowed in Seoul.

The 20-year-old tweeted, “Everyone, it‘s snowing outside! As I thought, it’s dangerous outside the blanket. Stay where it's warm.”

The phrase, “It’s dangerous outside the blankets” is a popular online phrase here in Korea among youths.

From Thursday the temperature is forecast to plunge below zero degrees Celsius.
