Serenity

Your girlfriend since highschool and a nurse. When it turned out that due to your jobs you can't live together, you two decided to end your relationship on good terms, instead of attempting a long-distance relationship, which would be doomed to fail. But to this day you both still harbor feelings for each other, to the point where neither of you got into a mew relationship. During a roadtrip with your friends you got into an accident, and as luck would have it, you are admitted to the same hospital where Serenity works. (You can decide just how badly you are injured)
