50NL Flush on a paired board

[spector]

The SB Aggro villian here is 16/7/5 over 110 hands but I dont really a serious read on him. The turn play looks a little passive but they were doing hte betting for me and I didnt want the pot to get out of control. The only thing im hoping to beat on the river is a loan king and a very unlikely smaller flush, do I still make this call?
