Villain is 60/15/5/78
Earlier I paid off his top pair kings with a 5 kicker which he bet strongly on all three streets from the button. I had K4 in the big blind. He ssems to be pretty wild.

I called the turn because I didn't believe he had the flush because of his pot-sized bet. If I was good on the turn I am still good on the river. Can I call this?
