The phrase "mischief me won’t hear" is not grammatically correct as it stands. It seems to be a jumbled expression. If you are trying to convey that mischief is something you won't hear or something similar, you might consider rephrasing it.
For example, you could say:
- "I won't hear of any mischief."
- "Mischief? I won't hear any of it."
