Weak Dragon’s Covenanted Harem

Born the trueborn heir of House Sassuolo, he can't even cast a blood pact. His half-brother Carlos, the family's "dragon prodigy," beats him into the dirt and calls him a broken cripple. As he lies bleeding, his blood wakes an ancient dragon ring, and a strange power binds to him: the Mate-to-Power System. It can repair his shattered dragon soul, but only through intimacy with the women bound to him. At the clan's blood pact ritual, the patriarch gives him a death sentence: reach Tier 5 in three days or be executed. Everyone expects him to claim elite slaves. Instead he picks the three "useless" ones nobody wants: an elf, a vampire and a fox-girl. The court mocks him for it. Then he tears up their blood pacts and refuses to force them, even with his own life on the line. Their affinity starts to rise, but the system rewards stay locked. With three days on the clock, his only way to survive is to win their hearts for real.
