The story is so good !! It is slow at first but the pace picks up. The story is full of fun and comedy, very light hearted at first ! I think the friendship between Shisan and Zijin is natural, the gradual trust and bonding between the two are sweet. Shisan's experiencing internal turmoil to achieve immortality or not was executed well. Zijin actor is very good at expressions, especially when showing sincerity. Zijin actor is the perfect cast for him, since his features exude kindness, and naivety at the same time. Shisan actor is amazing at body language, at one point it is very noticable.
