Bad Words Onions

Is there an onion that understands human speech? (really?)
They say that if you say good things to an onion, it will grow well, and if you say bad things to it, it will not grow well.
To see if that's really the case, I'll try an experiment.

Say a word while watering the onions.

“Oishikunare ლ(´ڡ`ლ)”
no,
“I love you onion~”

Observe how the onion grows according to what I said!

* Onions can grow strangely depending on your words┏(ºдº)┛
