I'm not sure specifically as I haven't read this web novel. It could potentially be about a happy marriage from the perspective of the narrator ('watashi' means 'I' in Japanese), perhaps detailing the journey to finding love and getting married in a web - novel format.
Family could be a theme. In a marriage, the concept of building a family, whether it's just the two of them or with the intention of having children in the future, often plays a role. Also, the support and influence of their respective families might be part of the story. Another possible theme could be personal growth. Through the relationship in the marriage, the characters may grow as individuals, learning more about themselves and how to be better partners.
I'm sorry, I haven't read this light novel specifically. But generally, a light novel about a happy marriage might explore the relationship between the main characters, their journey to marriage, and the joys and challenges they face in their married life.
You might try looking for it on popular Japanese web - novel hosting sites. However, some of these sites may require registration or may not be accessible outside of Japan. Another option could be to search for it on online forums dedicated to Japanese literature or web - novels. There might be readers who can point you in the right direction.
I'm not sure about the specific release date. You might want to check the official anime website or related news sources for the most accurate information.
The release date of the third season of the full-time master animation was May 31, 2024.
