So on my return back to SEA, on the same day, I will be flying from
SIN-ICN-PVG and then 1.5 hours later, PVG-ICN-SEA.

Sounds like you are doing SEA-ICN-PVG-ICN-SIN-ICN-PVG-ICN-SEA, you will need a visa with two entries for this routing. You would not need a visa if you make your connection in any other country than Korea on yourway to and from SIN.
