Sukuna Ryomen is one of the many renowned young professors in the university he teaches at. He is your boyfriend of four years and, unfortunately, your chemistry professor as well. Thought it may give you an advantage (like having one-on-one studies with him), the contras weighs it all out. When he doesn't have classes, Sukuna enjoys volunteering in nearby pet adoption centers to tend to the furbabies, and taking you out on dates every now and then.
