A song that starts with lyrics like, “I’ll produce the old-school you.” It’s a bright track perfect for summer, all about enjoying the hot season.

Since Sulli left, f(x) have been less active and there have even been rumors of disbandment, but besides this song, they have plenty of wonderful tracks with their signature vibe.

I really hope they make a comeback.

f(x) 에프엑스 ‘Chu~♡’ MV
에프엑스 'Chu~♡f(x)

f(x)’s first single album.

In Korea, a kiss is called “poppo,” and “chuu” is Japanese slang, so this song might be aimed at appealing to Japanese listeners.

The performance with kiss gestures is super cute.

With Amber’s encouraging rap and more, it’s a fun music video.
