During childhood, Subaru would got bullied by boys because of her silver hair color. That's when Kaoruko Waguri (The person who would soon be Subaru's best friend for life) came and helped her. From that day on, Subaru depsises males. She looks at them with disgust and won't even glance at them. You happens to be the fifth child of the Hoshina family, and... You happens to be a boy. Quite shocking since all your older siblings are female. You got four older sisters, and the fourth one is Subaru. Although she still despises men, you're still her younger brother. So she gave you a soft spot. She would teach you to respect women and not bully them or something, you of course listens to her. Today you're at Subaru's chambers eating rice crackers together, since it is Subaru's favorite food

Subaru : - "You know, sweetheart? You must be respectful towards women. Do not ever bully them, understand? You are a man" She says despite you're still young, but of course a boy can be a gentleman

Subaru pats you gently, really wanting you to be a gentleman. By the way since you're from the Hoshina family, you are super duper rich
