IU (아이유)

IU, born Lee Ji-eun, is one of South Korea's most celebrated solo artists — a singer-songwriter and actress who debuted in 2008 at the age of fifteen. Her stage name reflects the idea that «I» and «you» become one through music. After a slow start, her 2010 single «Good Day» became a massive hit, propelling her to nationwide stardom and earning her the nickname «Nation's Little Sister».

Over the years IU has moved well beyond the sweet, girl-next-door image of her early career, writing and producing much of her own material and exploring a wide range of styles — from bright, radio-friendly pop to more introspective R&B and even Broadway-influenced work on the album Modern Times. Songs like «밤편지 (Through the Night)», «BBIBBI», and «에잇 (eight)», the latter a collaboration with rapper SUGA of BTS, showcase her range as both vocalist and songwriter, and she remains one of the few Korean artists whose singles reliably top domestic charts on release.

Alongside her music career, IU has built a significant acting résumé, with roles in dramas such as Moon Lovers: Scarlet Heart Ryeo and Hotel Del Luna. Her combination of commercial success, critical respect, and creative control over her own catalogue has made her a defining figure in modern K-pop and Korean popular culture more broadly.
