I must say, this is an interesting concept for a story. After giving it a read, I was really interested in it. I especially like how you have made plenty of pathways leading down different media for different shows, allowing the reader to read about whichever character they have as a waifu. I do wish, though, there were more chapters. But that's hardly a fault of yours. Despite that, I would like to make two suggestion.

SUGGESTION: I see you have 'other' as a genre. May suggest you have that to 'family' instead? This would allow more people to find it, and it makes sense as the story is about marriage. You also have in your rules, children will be aged to 16. I would suggest making it 18 at the youngest, to prevent any idea that you are married to a minor.
