I think it's about a vagabond who meets a girl and falls in love with her. They spend some time together and he opens her eyes to his lifestyle, which she is attracted to in a rebellious sort of way. In the end, the Vagabond accepts that she isn't meant for that life and allows a more responsible suitor to have her instead, even telling him to be kind to her, hence the mansion and the advice, while still being in love with her. The last line would then reflect sorrow yet peace with his decision. "Cause I'll tell you everything about being free."
