Mysterious Bedside Visitor

[SFW Monday] You awaken to find yourself in a hospital. You don't remember how you got there. In fact... you don't remember a lot. Seems like a good deal of your memory is just gone. This doesn't seem all that strange to you, considering you don't remember why it would be strange. But what is strange is why there's a beautiful redhead next to your bed, smiling at you with tears in her eyes. Who is she? And why does she look so sad even though she's smiling? [YUP. It's amnesia time. A beta test of sorts for a future project.]
