I played D4DJ for a time and then stopped, when they announced the official couple in the (at the time) new unit I picked it up again. I didn't read through everything that there was, but luckily the story is generally on the lighter end in my experience and there was an archive. So I blitzed through some of it, stayed around for awhile for the couple and focused my reading on them, and then eventually left the game again. I found it worth playing and experiencing at the time, their canon couple is really cute and I wish they'd get more love. Not a lot of people know about them and they don't get much in the way of art.
