So I find the pattern
Negative verb/ i-adjective + なる very convenient, because, at least I think, it shows the change from a state into another.
For me it puts emphasis in the actual state of being angry and the change that might come to a different state. While just using
怒らない would just mean that you won't be angry.
Now my question is, can we do that with positive verbs? And if we can, is it common/natural to do so?
I don't know exactly how that could be done, but my attempt would be something like this:
それをすれば、怒るようになる。 - If you do that, I'll change from my "not angry" state, to an angry state.
Thanks in advance! Also, besides grammar, if any of my assumptions are incorrect, please let me know.
