(Prince of Tennis) Why Is Your Sister Like That?

Tezuka Kunimitsu is sixteen this year. He may be a little reserved, a little tall, and a little more mature ♂ than most, but he's still just a kid about to start high school.

So he's been under quite a lot of pressure lately. Because of certain things.

Like, for example, some things.

"Tezuka, why is your sister like that?!"

"Tezuka, your sister actually did that?!"

"Tezuka, I never would've guessed! ... Tsk, your sister really is like that."

These kinds of comments are such a headache. What can he do about the way she is?

But some people have a uniquely surprising angle.

"Tezuka, what does your sister think of me? OVO!"

Tezuka: "???"

Tezuka: "She's not my sister. She's my girlfriend."

Everyone else: "?"
