Teen star IU will tour the country from June, giving her first solo concerts since she debuted four years ago.

The young singer is in such hot demand that tickets for the concerts sold out within 30 minutes of being put on sale Tuesday, her agency Loen Entertainment reported.

Following two shows at Kyunghee University's Peace Hall in Seoul on June 2 and 3, she will continue her tour in six other cities including Busan and Daegu.
