The two locations in the MV are quite the stark difference. From the bustling streets of Seoul to the contrasting quiet zone with nature in a forest, "Wi-Fi" illustrates the distance one has from each other as well as having the option to cut ties and disconnect just like wi-fi. Also just like wi-fi, you have to go through numerous radio signal waves to finally get a decent connection.
Yoon Jong Shin makes a very distinct yet familiar comparison between reality and the virtual world which is clearly relevant to today's digital-driven society. The song allows listeners to reflect on what is truly meaningful in life.
