Villain is 15/9, 3bet 3.7% and is a reg.

He's setting it up for an easy shove on the river, which I can't call unless I fill up, which I'd have to donk and he might not call. I have about 22% to fill up and he's giving me 4:1 to fill up. I beat nothing, right? Standard fold? Apologies if it is, weak tight tendencies are strong in me.
