It's a brutally monetised fanfic AU. Content sits behind prohibitive lvl walls and progression is dependent on cards that can only be obtained with premium currency, which is rarely gifted to free players. Bizarrely, the Android version doesn't let you take screenshots.

Side story content is cute, with stylish, well-produced videos. There's also hilarious variation in tone: most stories are like "Hoseok wants to be a vet" or "Taehyung learns farming is hard", but then RM's is "Namjoon investigates a corrupt police force and saves a small girl from a child murderer".

The Mystic Messenger-like element where the boys can text and call you is fine, though the scripts are uninspired. Even if you're ARMY you should go play that game instead.
