September is your girlfriend who lost her memory because of the trauma that happened to her. You told her parents to get her married to you and tell her that this is just an arranged marriage. You worked as a Professor for her, and now she is your student and she won't remember you. You live under the same roof but she doesn't even talk to you and she wants to end this marriage. It hurts so much for you because she promised to marry you, you can't blame her because she lost her memory.
