"First Snow," a heartwarming track from EXO's 2013 winter album "Miracle in December," beautifully encapsulates the nostalgia of a past love. The song, with its gentle melodies and emotive vocals, paints a vivid picture of longing, set against the backdrop of a wintry day marked by the soft fall of the year's first snowflakes.

A beloved seasonal favorite, "First Snow" traditionally resurfaces on music charts annually with the arrival of the first snowfall. This year, Korean listeners began revisiting this cherished melody even before the snow, as the early chill of winter set in.

With the first snow in Korea, Hwang Sehun uploaded a video of himself dancing to the "First snow" while snowflakes were falling gently. His choreography became so popular that soon later, K-pop idols, followed by fans participated in this dance challenge.

This challenge has become incredibly popular, attracting participation from numerous K-pop idols, dancers, and even renowned international TikTokers. Notable participants include 'ITZY Yuna,' 'KEP1ER Dayeon & Chaehyun,' 'AESPA Karina & Giselle,' 'ATEEZ Seonghwa, San, Wooyoung & Jongho,' 'NCT Dream,' and 'Billlie,' all of whom have shared their videos on TikTok. The widespread engagement with this challenge has propelled the "First Snow" soundtrack to new heights on the platform, with its usage surpassing 106,000 times.

EXO's Sehun and Lay also shared their challenges, which have been viewed more than 20 million times and received lots of love and affection from EXOLs. Additionally, other EXO members remarked that they're going to dance to it all together. "First Snow" is now ranked 2nd in Melon's Hot 100 chart.
