This pop-up is highly significant as the starting point for the long-term MIGHTEEZ IP business that LINE FRIENDS and ATEEZ will jointly develop. Previously, a pop-up store commemorating the release of ATEEZ's 12th mini-album 'GOLDEN HOUR : Part.3' was held at LINE FRIENDS Square Sinsa, Japan, the USA, and China last June, and it successfully concluded with great enthusiasm from fans due to the collaboration between LINE FRIENDS, which possesses strong K-pop IP business capabilities, and ATEEZ, which boasts a global fandom.
