The length of the stroke on the left and the vertical stroke on the right should not be too different.
The vertical skimming on the right side should not be too oblique.
The distance between the left and right vertical strokes should not be too small.
Can you imagine "は"? This hiragana, "け" and "は" are only slightly different in the last stroke.
"け" is "は"? Finally, I stopped writing.
