How long has it been since your waifu last received new material? I don't mean so much merch, but rather something that broadens her universe and/or makes her plot advance: anime seasons, OVAs, anime films, videogames, novels. In my case (pic related) it's kind of complicated: the final version of her VN was notably released in January 2012, but a different version of the VN was released in 2017: this new VN consisted mostly of scrapped official ideas which were collected and assembled in an unofficial manner by fans of the series. So, a formally fanmade product using genuinely official material which could have made it to the final version (but didn't). That means it has been 7 years since the last time she received canon(-ish) material. The original VN from 2012 was also recently re-released via Steam, but without any substantial changes, so I don't consider that to be new material.
