The characters are all well fleshed-out and interesting, and the humour is especially great for anyone who has played otome or dating-sim type games before.
What made the series especially great for me though, was the inclusion of the 'real life' sections. I don't want to spoil anything, but showing the reality outside of the game gave us a beautiful and tragic story, allowing the in-game plotline to be far more interesting and sweet.
