[General] He's a rather shady person.

[Silverobama]

Hi teachers.

Someone cheated me a few times and I don't think he's trustworthy. Is it natural to say "He's a rather shady person".

If you think someone is shady, you are unlikely to put yourself in a position where they can cheat you even once.

He's my cousin.

"He's a rather shady person".

I wonder if this sentence is natural.
