I think it's just from when he lived his second life where its only proper for a girl to adhere to societal rules like guarding yourself against blah blah blah. It's stupid I agree ahaha but I think he will come to learn on how the modern world operates now. Poor guy.
But its cute to see how overprotective he is.. I wouldn't want to be his kid sister tho (⊙…⊙ )
can't belive he seriously considered having her quit her dream job for something so simple.. she's an adult now, she should be able to do what she wants but it's still a little cute how overprotective he is
