The sonnets begin with the narrator's petition to the fair lord, exhorting him to preserve his beauty for future generations by passing it on to a child. This theme is developed until sonnet 18, where the narrator abandons it in favor of an alternative plan to eternalize the fair lord's beauty in his verse. But it is not long before the narrator's mellifluous depictions of the fair lord's beauty are replaced with the haunting lament of unrequited love. The narrator grows increasingly enamored with the fair lord, eventually becoming emotionally dependent upon him and plagued by the inability to win his heart. The narrator is further distressed by the incessant passing of time, and he fears the detriment time inevitably will bring to the fair lord's youthful beauty.
The narrator's emotions fluctuate between love and anger, envy and greed. We find poignant examples of the narrator's jealousy in the rival poet sonnets (79-86), where the fair lord's attention has been caught by another. The narrator's fragile psyche collapses in bouts of self-deprecation as he agonizes over the thought of forever losing the object of his affection. In sonnet 87, the narrator bids the fair lord farewell - but his heartache long persists.
The remainder of the fair lord sonnets are characterized by the vicissitudes of the narrator's emotional well-being. After his parting with the fair lord in sonnet 87, the narrator grows introspective, waxing philosophical as he begins to probe the very fabric of love.
