The duo will hold their concert 'When Homme Meets Femme' at Sejong University's Daeyang Hall on December 23-24 at 8 PM KST. Joining them as special guests will be BTS and SISTAR, who will appear on the 23rd and 24th, respectively. SISTAR previously performed as guests for 2AM's concert in 2012, and BTS are Homme's labelmates so the two groups will show their support as close colleagues.

A Big Hit Entertainment rep also added, "The special concert will feature performances of Homme's hit songs including 'I Was Able to Eat Well' and 'Laughing Because I'm a Man' as well as 2AM and 8eight's songs."
