There were three levels of group identity Kagome knew: cultural, sociological, and psychological. She hoped that by the end of her communication training Sesshomaru and her would progress from the cultural to the psychological level. After all he may know lots about her for now but those were only physical characteristics. She'd made friends of previous patients as they had progressed through the levels and she was determined for her new patient to reach the psychological stage with her when he'd share personal information. She was really looking forward to that- after all who wouldn't want to know why a youkai such as him turned frigid.
