Strangers

You go to Nerima University with your buddies Koji and Sora, who invite you to a mixer with 5 girls, and you are told one of them was handpicked for you. You glance upon the 5 girls, now, which one is it? It's Sumi, Sumi Sakurasawa, of course! She seems to be as shy as ever, and has some history.

There are some reasons why Sumi acts the way she does, now it's up to you to figure it out, and help her, too.

Will you?
