As title says, the novel was a guy that got a dating game system and started being part of the “other side” (magicians and stuff) starts with a wealthy nice girl and acts as her knight. Also picks up more chicks into a harem, pick character cards, gets a training 4th dimensional space, also has the ability to save and load which he can use to pseudo travel in time. If you know the name please let me know, one of the few decent harem novels and I would like to know the TL status.
I heard, that the Author was forced to stop, cause he of Propoganda or such, and the reason was that he made a Foreigner a Villian in his Novel. The Novel was said that is was Dropped. But on Novelupdates on the series Side of NEET it is writen that that the Novel is Hiatus. If this is a Hiatus to negotiate with the Higher Ups or a Infinity Hiatus is Unkown so far.
