But now seriously, I'll try to address your misconceptions:
That's not a haiku
It is.
it needs to be 5, 7, 5
Not really. That's like the definition for kids in school, simple but not 100% accurate. There's plenty of haiku with different metrics, even single syllable lines.
not 6, 7, 4
I count 5-7-4.
The separation of lines matter
Iirc in Japanese haiku are written in one line.
You are kind of right tho. I think it sounds better like 'He just kicked him out' but I was trying to making it just taking out words from the original post.
