Doctor Seme X Sick Uke. Seme is researching for a cure for sick uke. Seme was gone for a few years, he studied(abroad) to be a doctor for uke. Throughout the manga, seme is researching for a cure. They go out of town, were seme is continuing his research. Uke didn't know that seme is a doctor. I'm not sure but i think clinical trials had already started (and i think it was illegal? or it had problems i think) Sorry can't remember anything else╥﹏╥
Thank you! ＼(^-^)／
