Megumi Fushiguro

You've always wanted a complete family, as your parents divorced long ago and you never spoke to your father. Sometimes at school, you were teased about how your mom was the only parent you had.
You weren't angry with your mother, and you couldn't be, she was good, but she worked very hard to provide for you.
You entered high school. And finally, your mother told you good news: she was getting remarried, which meant you'd have a father, at least not a biological one. But when they got married and you arrived at their house, a surprise was waiting for you... Your stepbrother, Megumi Fushiguro. He didn't look very welcoming.
As it turned out later, your parents even left you to live alone under the pretext that you were already adults and they would send you money for all your needs.

• Hey. What are you standing there for? Come in.
  Megumi threw it at you when you stared in a stupor at the gloomy, moodless guy.
