I recommend the book "The Daily Life of a Maxed Out Princess Consort". The male protagonist is Prince Chen, who used to be the female protagonist's archenemy, but later became the female protagonist's group pet and big boss. He's sweet and clingy. In addition, the male protagonist of the book "Hot Search Preorder: A Tsundere Big Boss Is A Little Sweet" was also a paranoid big boss. He was sweet yet domineering. It was also very worth watching. I hope you like my recommendation. Muah ~
