On October 31, YG Entertainment shared the actor's final thoughts on his behalf with, "'Scarlet Heart: Ryeo' was a production that was made with a great director, scriptwriter, actors, staff, and everyone. Those 6-months of living as Baek Ah was real happiness. There were difficulties because it was my first historical drama, but I always had fun with the brothers. Especially the scenes with all the princes. We played around a lot and became very close."

Nam Joo Hyuk also shared a comment about watching drama whose filming was completed entirely beforehand. He said, "I missed the drama set a lot while watching the broadcast. I also became one of the viewers and shared the sorrow when I watched my brothers die one by one. It's going to be another drama that I will never forget. I hope there will be a time for us brothers to reunite soon."

The last episode of 'Scarlet Heart: Ryeo' will be airing November 1.
