Awesome game
I decided to play it after I watched the series and soon it became one of my favourite otome games. From the art to the story, game mechanics (which make it really easy to miss out on events, CG's or even get you into the route of one guy instead of the one you are aiming for) interactions between characters, time management, amongst others. It is also good for those who like myself are learning Japanese, as the subs are somewhat easy on the eyes and the writing style is simple enough for beginners to start putting theory into practice. Of course, using a guide is still recommendable here to ensure you don't miss out on much.
