Similar to Sendai Ariki: Female Master and Male Disciple, Not Yandere, Not Crazy, Not Too Funny

I want a story like A Tree in Sendai about a female master and a male disciple. The male protagonist doesn't want to be yandere, doesn't read Prison, doesn't like crazy stories, doesn't want to be too funny, doesn't want too many jokes, both men and women are strong, and the writing is better. I'm really short of books, thank you🙏🏻
