I dont think so. I checked ch 1 and jiwon is wearing different clothes when taeho dies. Also he calls him taeho and up until now in past flashback he doesnt know his name only calls him mountain man..unless taeho literally translates to mountain man lol. I feel like its some fellow royal family member whos gonna be assassinated. Probably a crown rival or a rebel whos plotting to overthrow.

Brooo...this is were everything goes downhill:)the 1st person on the left is definitely taeho. I can't read the next chap
