Bubble service
Bubble is a paid service by Lysn provided by SM Entertainment's Dear U where by paying 4,500 won per month, users can reply by receiving messages, photos, and videos sent by artists.[10] For artists, they can see these messages in large group chats and reply to the whole group, but not directly to fans. For fans, the UI is like a personal chat between you and the artist.[11] Additionally, it offers a Dear U Bubble service that allows artists and fans to communicate.[12] The service offers in-app translation services to translate from Korean to English which similar platforms like Universe and Weverse have.[13] Since the content posted cannot be leaked from the service, artists tell "more profound stories", and fans feel that they communicate "more closely". Moreover, SM stated that the company is currently continuing to upgrade its functions by providing differential functions for individualization and loyal customers while also planning to expand its service through the participation of other entertainment companies.[14]
