This Time, I Chose the Dragon Who Loved Me in Silence

In her previous life, Stephanie devoted herself to training the giant wolf Claude, only to be betrayed by him and her sister Garcia, dying while the small gecko Alex, whom Garcia abused, gave his life to protect her. After rebirth, Garcia seized Claude, while Stephanie chose Alex and cured his curse. Alex, actually a divine dragon, transformed and protected her, exposing Garcia's abuse of magical beasts. Garcia was imprisoned for forbidden magic, and Claude became a crippled wolf. Stephanie and Alex married and lived happily ever after.
