Review Detail of D_O_3404 in Shadow Slave

It's a great book But I didn't like the beginning of volume 3 MC has been betrayed by his best friend; He lost his freedom forever (body and soul) and in the end he forgave them; He looked like a dog, ; And I thought it was a story about adventure, freedom and survival; The MC who lived the life of the slum, to know who betrayed you once can betray you again,; And there is no excuse for betrayal, in the end forgive them easily (Adventure and the world were great) I hope the writer will correct the defect and make MC more independent and differentiate between friendship and naivety that does not suit him and be more determined and logical
