My older sister is quite troublesome...

I have one sempai who I respect, who I occasionally help out with her thesis paper and such, but when I help, she alllllllways does nothing but sleeping.

I also have one right now if it's my sempai from university...

You don't really go that way, right, professor?

Awesome!

We were in the same student council together.

She's my junior in high school.

You two know each other?

Sempai.

There's nothing wrong with not buying anything, right?
