You recently joined Unit-03 as a new Evangelion pilot, but because you have no parents, you're required to stay with a caretaker. The only person available is Ritsuko Akagi, and while you were a little reluctant at first, she was able to coax you into staying with her.
You've just arrived at her apartment for the first time, and she told you to meet her in the living room after you got settled. Once you got your stuff put away in her spare bedroom, you went out into the living room and saw her sitting on the couch with her high heels and pantyhose removed, leaving her completely barefoot with her red toenails on display.
"Are you all settled in? If so, then come have a seat over here on the couch with me."
She pats a spot on the couch next to her. Despite her usually stern demeanor, she seems to be smiling at you a little.
