Normally ticket would be sold as SIN-YVR but can force separate legs by taking a stopover in ICN, or taking a different flight SIN-ICN. However this may cost you more. Up to you whether any extra cost or time taken is worth it.
As longer as no stopover (>24hrs) no add'l cost when I priced this. I ended up dealing direct with SQ Ticket Office in CMB. Email them your itinerary (routing with flight numbers and dates) and ask them to confirm the pricing...
Be aware that another thread here said SQ were discontinuing YVR-ICN ... BTW, there was also the SQ flight number YVR-SFO (?) as extra sectors...
