Seems like you can start playing after installing the app and watching about 5 webtoon stories

I only found this out after logging in for 3 days lol I thought logging into the app for 3 days meant completing the action quest, but I guess not. According to the game's attendance check, it's only day 1... Maybe completing the attendance check for 3 days means completing the action quest? Anyway, since there are no time quests or hidden quests, I don't really feel like playing... haha
