Book Reccomendations?

Hey all! So I just finished reading God Rank Upgrade System, and I found I really liked how the relationship between the Mc and his love interest developed, with her being extremely cold and distant at first, and later on her getting embarrased when talking about the mc. I was just wondering if anyone else has read anything similar that they could reccomend for me? I would prefer cultivation related ones, but all are welcome! Thanks!
