Reader note

Both have the male protagonist go dark and the female protagonist returns to the small world, which fits your requirements very well. Two serialized books, the rating is slightly lower because they are being serialized, but they are very interesting. I am following both of them. One is a completed novel, with a rating of 9.0 Or above. You can read the introduction first, and if you think it's good, you can continue reading~

Reader note

These are all three books, and there is another one called The Master of Levels Returns to the World of Fast Travel. The heroine is Chacha. I can't find it. The second one is my favorite, you can read it.

It's a quick story. The female protagonist is strong and gentle. The male and female protagonists love each other very well. I highly recommend it. It's super good-looking and super sweet. It's a pairing for life. It has many aspects and novel themes.
