On the March 18th installment of 'Open Concert', Gugudan stood on the stage to perform "The Boots" title track from their 2nd single album, 'Act. 4 - Cait Sith'. As they wrapped up, they were met with loud applause from the audience. In addition, Gugudan's Kim Se Jung harmonized with the very talented Paul Kim to sing "Flower Road" (produced by Zico).
