The older brother of the pair Lee Chan Hyuk stated, "Because YG is a big company, it has professional and top notch equipment. Thanks to that, we are able to make more diverse arrangements. While we're working, there are also many talented music technicians that stand by and help us. Back in the days when we only had a guitar, whenever we wanted to try something, there were cases where we couldn't. Now we've put aside the guitar, and when we want to arrange something, there are people who advise and make it happen for us."

Lee Chan Hyuk continued, "We absolutely have no regrets on choosing YG," referring back to their 'K-Pop Star' season 2 win, when they were able to choose among the top three entertainment labels, YG, SM Entertainment, and JYP Entertainment. 

Sister Lee Soo Hyun added, "The environment has really gotten better. Whenever we want to practice, we can do so at the office; there's also a rehearsal room in front of our house, which allows us to practice singing and do our job comfortably." 

She recalled, "There were times when we even woke up at dawn and headed towards the rehearsal room," showcasing their passion for music and how YG grants them an outlet to express themselves.
