FIESTAR's Jei, Cheska, and Cao Lu has another Korean slang to teach their overseas fans for their new lesson of 'FIESTAR's A-HA'.

Korean word for the day is 'gaenso' it was derived from the Korean phrase, 'gaein sojang' which means it is a collection of information whether private or personal about yourself. It is used when you want to treasure something on your own.

On this episode, FIESTAR also announces their upcoming comeback this November 1. They were excited about it and also gave a hint on what fans could expect on their new songs.

For the meantime, hope that FIESTAR helps you understand better what the Korean word 'gaenso' means and use it in a fun way to interact. Hope you enjoy another episode of FIESTAR A-HA. Till next episode. Fighting!
