Finally got around to reading this, and I think it's your most mature VN I've read yet - both in subject and quality of the writing. The artist did a great job making Bell luring in every picture she's in. And that ending!
I also had a 'rough patch' with my wife and was confronted with temptation, so I can very much relate to Robin. Thankfully, my wife and worked things out... but I also wasn't pursued by a cute cat-girl, so who knows how things might have turned out different.
