200NL Weird spot vs overaggro villain on river

[VPIP100]

Villain is extremely aggro and makes huge overbets.
I 3-bet KQos OOP once, c-bet T84 flop and he shoved.
He shoved alot when scare-cards hit (flush/board paired), but he has not been called yet.

He is 60/21 and aggr by street are 2/infinite/3 over 100 hands.
