@Outinthegardener Ehh, all jokes aside, this isn't necessarily Raufreg showing masochist tendencies. This is him falling in love with Hannelore specifically, it wouldn't necessarily happen with any woman who beats him physically. Also, this is a culture where it is acceptable for women to physically overpower men and profess their love for them. Raufreg's behavior isn't all that strange or unusual in that context.
This is less of a "beat me mommy I love it" moment and more of a "my gosh you are strong and awesome, please marry me" moment.
