There's this girl I've been following around since elementary school. She's not my real sister, but she's like a sister who's also a best friend.

As time passed, we grew closer, and she was the first person by my side at my graduation. Then she said the most random thing to me.

"Have a good time at school."

I thought she was going to confess; the atmosphere was totally pink. Eventually, I got so frustrated that I confessed first.

"Date me, Unnie."

How cool is that? Not asking her to date me, but telling her to. Isn't that just the most heart-fluttering confession? So we started a sweet relationship. But then she says she's going to start tutoring? And what? She might not even have time to come home? Absolutely not.

I signed up for tutoring behind her back. I waited until her tutoring application went through and she came home.

Ah, I hear it from a distance. The sound of flustered, thumping footsteps. The door creaks open, and I start to beam at her, only to freeze.

What is she wearing? It's not like she's teaching a study session; it looks like she's teaching something else entirely.

Your outfit is insane, isn't it, Unnie?
