After building up the drama about DoJun for 15 episodes and suddenly killing him off towards the end was a bit lousy writing. All this time I was expecting to finally see Dojun buy Soonyang and sit on the throne that he has been fighting for his whole life. Suddenly shifting the plot towards Hyun Woo for one last episode when the entire audience was invested in the story about DoJun was pointless to me. But as Hyun Woo mentioned towards the end the story wasn't about possession or time traveling rather it was about his repentance towards DoJun and himself. So I guess this whole time the plot was from Hyun Woo's perspective, which kind of makes me not dislike the entire drama just for one episode which didn't go as I expected. I mean we all kind of knew DoJun was dead but we still kinda hoped for some sort of miracle lol. Overall, I think it was a great watch, the twists after twists and all the mind games played by the protagonist, and not to forget the outstanding acting and the beautiful relationship between the grandfather and his grandson, so damn wholesome! If I would ever give this drama a rewatch it would only be because of the grandfather and grandson duo. In the end, it wasn't about revenge but rather justice for DoJun and his loved ones. Everyone in Jin's family kind of got the taste of their own medicine which was very satisfactory to watch. But what was the need for identical characters and how come nobody ever noticed how similar they both looked? :/
