100nl- 99 on low monotone flop

[Nikachu]

Villain is like a 42/8/2.2. I played two other hands with him where he donk led the flop and called a large raise. On both hands he check folded to a continuation bet on the turn. I felt pretty confident that he didnt have much in this hand. Kinda figured maybe he had a little something with outs like 56 or Ah6x.

Does my line look sound?
