Like you said, I suspect very little. Shinkurou may believe she's just a child repeating what she heard on the television or from Tamaki/Yamie which would be correct for a lot of the cultural things Murasaki has absorbed since she was in his care, but Murasaki was taking all the conversations with the two women about relationships absolutely seriously. Tamaki and Yamie were telling her things they actually believed (especially Tamaki after her little episode at her college).Originally Posted by Everon
If anything, Shinkurou may believe he's just speaking with a child, but in terms of relationships/romance/love, Murasaki is anything but. Mentally at least. This has been bred into her for years.
