My OP Dragon GF Can’t Fight

A young and courageous man, known only by his first name Alexander, whose origins are shrouded in mystery, awakens a slumbering dragon and forms a binding contract with it, becoming the protector of the Celestian Village. As mysterious as his background, so is his voracious greed. For wealth, fame, and power, Alexander was willing to go to any lengths and believed that everything in existence serves to amplify his gains. Alexander's expectations of wealth and glory after awakening the dragon were shattered when the cowardly creature proved to be weak. Now facing formidable foes, must he choose between courageously defending the village or succumbing to his greed and losing sight of his true purpose? Because every body part of a dragon, when ingested, grants power, including its POOP. Like every creature, this dragon too shits daily, he has a lot of chances to gain power, albeit in a SHITTY way. ... "Alex, you spend so little time here. What have you been up to?" "Oh, just a few things. You know I have a life outside this whole dragon servant thing." "You didn't think about that when you signed up for this!" With a smirk, Alexander teased Krystal, asking, "What's next? Are you going to chase me away?" Despite enjoying his company, Krystal was speechless, torn between her feelings as she enjoyed his company. Perhaps Krystal had grown overly fond of Alexander, giving him a sense of bravado and cockiness.
