Drama where lead is seen as scary/cruel by others but actually nice/kind?

Looking for where lead is mistakenly seen/perceived as scary/cruel but is actually nice.

Historical/modern is fine. 

Basically lead is kind/nice inside but their exterior or actions make them look like they are cruel/scary/heartless.

ty in advance

The Wolf - ML's behavior is cruel so he's not exactly 'mistakenly' perceived like that but deep down he is kind (or it's better to say that his intentions are not evil).

Flower of Evil may fit as well.
