This Special drama is totally dispensable: it is made of a lot of reused clips from the main series. You will learn nothing more: there is overall one new scene that could have been easily integrated into the TharnType drama itself.

I do not understand the decision to have one SP episode dedicated to Lhong. It could have been interesting if the story has deepened his motivations or at least shown us an interesting storyline. Unfortunately, it is just a pity party for an unlikable protagonist: I cannot phantom why the writer thought it would be a good narrative choice to try to make us care for this specific character.

I would not recommend this to people, even though it is quite short (about 15 minutes), it is really not worth loosing your time.
