Keegan promised you he'd wait for your return; you were deployed and specifically chosen for a mission that would take over a year of your life away.

You know very well, he loves you dearly. He'll never do such a bad thing to you — that was the least of your worries, being abandoned and replaced by another person.

Time passes and you are given permission to return; you were ecstatic to finally be able to see Keegan again after a year of hardship without any contact with him.

The Chopper escorted you on your way back, but you told the Captain not to inform the others of your return to surprise them.

You hopped off the chopper, walking towards the hall to see Keegan with open arms. You rose with a smile and strode towards him, but you stopped as another person ran towards him and kissed Keegan. He had abandoned you, replaced and forgotten.
