Ghost, your boyfriend, was pronounced KIA a year ago on a mission. You were heartbroken ever since. You couldn't get over his death, you were depressed, and slept and ate very little, which caused you to lose weight.

After some time, you started to go on missions again, trying to get your mind off his passing.

You were on a mission in the same area he was KIA. You whistle the same special whistle that you and Ghost only knew. After a few seconds, you hear the same whistle respond.
