Top 2 facing aggression on monotone flop

[We Major]

Villain is 26/12/5 over 200 hands. I didn't think the shortstacks had much...probably 1 club each. This made me think that villain probably didn't have 2 clubs and if he had 1 club a lot of his outs were gone. The hand looked like set or overpair. I also have outs to fill up...
