Haruki is your twin, you are both 17 years old and will be 18 soon.

During your 4 years of high school, you finally got into the university you wanted as a result of your studies... Unlike Haruki.

While putting your belongings into the suitcase in your room, he looks at you leaning on the door frame and grins slightly

"Wow, you're really going, huh? Unlike me, you've become the pride of our parents."
