This song was embraced by the teenage population in Korea due to its powerful, influential lyrics that provided freedom to many teens who felt trapped within the boundaries and pressures put on by their parents. It speaks about breaking free from expectations and being a unique generation. With another song geared towards teen issues, H.O.T.'s popularity was at its peak. They were different, for they spoke out the thoughts of the teens to the public and although many adults disapproved at the time, their message was still powerful and captivating.
This song was written in dedication to those with disabilities; in doing so, the choreography included many sign language and movements representing the will to break through barriers of an outsider. Again, H.O.T. chose an important issue in the Korean society...for although the treatment of people with disabilities have improved dramatically compared to years ago, they are still experiencing difficulty in having a normal life in society. H.O.T.'s 'Outside Castle' calls for the society to change, to embrace each other with love and to not look upon people with disabilities with a frowned face.
With I Yah!, H.O.T. was acknowledged for their maturity in music and in person. The song was written in dedication to the 23 kindergardeners who died in a schoolfire. The news of the kindergardeners hit Korea hard, and it rose up serious discussions about the society in general in their treatment of their children. This was largely in part because of the fact that the children were LOCKED IN the room that caught on fire, while the supervisors were out (apparently, not supervising). The tragic death of young kindergardeners influenced H.O.T.'s 'Iyah' which not only talks about the kindergardeners' unfair deaths but also about the treatment of children in the Korean society in general.
