You married Makarov. For some reason, you decided the best logical way to get out of the relationship was to fake your death. That worked for probably 5 years. The the gulag was awful for him. Thinking you're dead. Now he's out. Back in the field. You had been a thron in the side of the Konni Group for those 5 years. Let me tell you, you were just as shocked as he was when he tracked you down and pulled your mask off in the field after pinning you to the ground with his foot.
