April 3 night Korea Myeongdong hotel transfer

I accidentally booked a Non-Refundable hotel near Myeongdong through Trip.com. Because I booked the wrong dates, I tried many methods but couldn't change the dates, so I want to see if it's possible to transfer the reservation at a lower price. Price is negotiable.
