Here is my git status look like:

Staged changes

1. Change 1 in file 1
2. Change 2 in file 1

Unstaged changes

1. Change 3 in file 1
2. Change 4 in file 1

Now I want to remove Change 1 and Change 2 completely, while leaving Change 3 and Change 4 in working tree.

I want git status to look like:

Stage Changes:

N/A

Unstaged Changes:

1. Change 3
2. Change 4

How should I do it?
