Since we don't have the actual story, it's difficult to determine the main character. However, if it's a story about love and sacrifice, the main character might be a person deeply in love with their invisible mate. They would be someone willing to face all kinds of difficulties and challenges in order to free their beloved. It could also be a character who is on a quest for self - discovery and realizes that freeing this invisible mate is part of their journey towards understanding themselves better.
