After Rebirth, Live a Good Life with a Disabled Veteran

In his previous life, Yan Huai was brainwashed by his family and always thought that he was just a BETA, so he willingly donated his blood organs to his fragile brother Omega. Before he died, he realized that not only was he a precious OMEGA, but he also had unique special healing powers, but all of them were taken away by his brother. The elder brother became the light of the empire and married the crown prince, and he, a humanoid blood bag, was forced to marry the violent and gloomy eldest prince who was disabled in the war. But when he was about to be executed, it was the legendary gloomy and violent eldest prince who risked his life to lead him out of prison. On the day of rebirth when he married into the royal family, Yan Huai showed a bright smile when faced with the family members who persuaded him to give up the crown prince to his brother: "I will marry!"
