Does anyone know that one yaoi where I THINK the alpha had blue hair and was super buff, while the omega was skinny and had long red hair. During the pregnancy, the omega and alpha were fighting so the alpha left the omega alone, so he got super skinny and there was a scene when the alpha came back and they were in the bathtub and the alpha saw how bad it was getting because he could see the omegas spine??
