I need someone to help me find the name of a drama. I can only remember the ending so Idk how helpful that'll be. 

The ML was waiting for his girlfriend (FL) to show up (I think they were moving in together or leaving the city) but she never showed up. We the audience got to see her get attacked in the woods I believe as she was heading to the ML. Fast forward years have passed and the ML is old and I think he's a professor. His old friends come visit him and tell him they finally found his girlfriend (FL) body. As they are telling him this they show his younger version so the audience knows who the guy is.
