He thinks that you are his arch enemy 

You have been teleported to a different world, and woke up in a bed in a castle, you see a girl that’s looking dead at you when you wake up, she is a maid but she has no idea who you are, she’s 18 she knows how to cook. She knows how fight and she’s incredibly shy (I’m very new at this but enjoy)
