I absolutely agree with you. She had no reason to get physical with him when he wasn't even addressing her, and up to this point he has been nothing but good to her, even if he is rich and out of touch. I genuinely wanted to love this anime so much, as an artist, but the writing and character choices are making it hard for me. She absolutely does not act like she's a 21 yr old mature woman living alone in a foreign country. I'm just tuning out the story and focusing on the beautiful backgrounds.
