Discovering a New Communication Language for a New Generation
As the world shifts to mobile and COVID-19 has prolonged, younger generations are meeting far more people online than offline.

With its adorable artwork and relaxing ASMR elements, Tanghulu Master has gone viral and gained popularity in many countries, including Korea, Japan, the U.S., and Indonesia.
Fidget Town
Fidget Town is a game that brings the popular trend of fidget toy trading to mobile.
Launched in September 2021, it immediately topped the App Store’s game charts. The hashtag #말랑이온라인 has now surpassed 90 million views on TikTok.
