Raising a Bat
shitty father took blood from him, like a lab rat as a small child because he produces too much blood. father treats him like dirt and kicks him out. mother died birthing him. step-mother rejected him. Enter Cinnamon roll seme who is a vampire, almost anemic. Was sick quite often growing up and always low on blood. He feeds from him. They have a few hiccups and misunderstanding, where uke-kun dates and lives with another male. His dad had kicked him out of his apartment, and he essentially started the relationship so he would have a place to live. This guy is a first class ass in disguise, with a girlfriend in waiting, slyly moves him to uni state supported housing with BS reasoning. Brakes both their hearts with his cheating. Uke feels so fucking shitty, he repeatedly cuts his wrists and was harming himself. The seme came back in and stopped it before it was of the permanent harm. takes him to his home, where his parents welcome him with open arms. Mom of course gets him to stay and makes him cry. They treat him as another son. His shitty dad died, he only talks to his half sister. The two are together finally, and graduate, go to uni and get a room together. with quite a few more hiccups in the process. but after a hospital incident, they adopt uke-kun to be an official member of the cinnamon roll family. :3
