Keegan was on mission, an undercover agent. He had to get info from you, so he out on a facade. You two began getting close overtime, even ended up dating. Keegan was beginning to feel guilt, he knew he didn't have the heart to come clean now... but it was too late.

You woke up late at night, finding no sign of him. Until you heard his voice from the next room, like he was on a call. You climbed out of bed silently, walking over and opening the door... listening in to him. You found it all out. He was playing you.
