After Hefa Got Engaged, Both the Apprentice and the Heroine Went Crazy

Have You Ever Developed a Yandere Villain Since Childhood? Ancient Saying: Master and Apprentice/sister and Brother/sister and Brother

I want to read a book like "The Cub Raised by the Cloud Turned Dark and He Plotted Mischief to Me". It doesn't matter if you have been raised since childhood. The male protagonist Shirakiri Kuro is a yandere who has been plotting against the female protagonist. The female protagonist is dedicated to leading the villain to the right path and finally fell. I really need it!
