What do you think is the best plot of "villains washing white" in film and television dramas?

In the TV series My First Half Life, Luo Zijun's ex-husband is a typical villain. His method of whitewashing is different from others. In order to get rid of his irresponsible image, he has been very kind to Luo Zijun and always takes care of all aspects of her life. The last two people lived happily. The plot of this villain's whitewashing is very consistent with our daily life and well designed.
