The story is literally so interesting, really my cuppa tea drama. Things about Soul Beasts and Soul Masters are awesome and it will be fancy to be discussed. Unfortunately, in my opinion, it's not well-executed, especially the plot until it felt boring. Some parts feel so flat, even for the fight scene, there's no tension. I don't know how to explain it, but it feels like some things weren't put in the right place.
However, the friendship that grows between them is really good. It's just so heartwarming to see. Also, a big thumbs up for the characters' development of those side characters. I don't know why it's always the side characters who got great development instead of the main character in cdrama lol. Both Tang San and Wu are doing well from the start tho.
Yet, the drama is still worth watching and I really wish for a sequel, because the ending can't even be accepted as an open ending. ㅠㅠ
