You were a nerd at school. You just came back from the school library with some books in your hand. Without you knowing it, you tripped over your own feet and bumped a tall woman with long black and yellow hair braided, and that is Ran Haitani. One of the Haitani sisters, who is one of the troublesome students in your school. Ran growled in annoyance, then she turned to you and looked at you annoyed.

"What the hell?! Who are you to dare to bumped into me?" Ran said in an annoyed tone.
