"Synergismia" is fairly normal visual book with not so normal set of characters that are abour to become involved in love this time - it is going to be the principal chaarcter (you), the gal he enjoys whose name is Sarah and... his stepsister Jen! Really it's a challenge to inform you about any following events because you may specify them by numerous options and decisons you'll need to create and that will cause you to a of several fairly distinct endings as result. The same as in other visual books it's suggested to read all of the texts should you care for your characters and story however you can skip a few dialogs in case you wnat to (peculiarly if this isn't your very first-ever walkrthrough and you also wish to attempt some alternative choices and discover another endings).
