Secrets and answers (Rin okumura x Oc)

Bet part 1~

After last week's fesival, Rin and I got a lot closer after what happened. Our test grade is tomorrow, yet somehow I feel weird vibes. We're changing seats today and sat next to Rin. Rin turned to me and smiled, but something wasn't right. We was in the middle row to the window. I sat in the left while Rin in the right. I smiled back while Rin gave me a note.
Meet me after school. -Rin
I silently nodded because either way he will force me to meet him. The bell rang for lunch and did nothing but look at their lunches.
Every single day.
I quietly pretend that I wasn't hungry and listened to the conversation.
Like always.
Time skip (after school)
I was walking home with Rin and Yukio. Who seem to be arguing about something. Yukio stopped and answered his phone. He quickly hanged up and started running to the opposite way.
"Where the hell are you going, Yukio?!" Rin yelled.
"There's some demons at a girl's bedroom." Yukio yelled back to Rin. I was standing there like a statue like I never existed to them.
"Let me come!"
Pervert.
"Rin I thought you was going somewhere with Yuko."
At least he recognized me.
Rin quickly turned his head to me in complete shock. "Oops! Sorry Yuko!" I gave him a what-the-in-the-hell face. He shivered and grabbed my hand. I turned my head and see Yukio already gone. I looked at their building and started to invite me in.
We sat on the floor and he started to talk.
"You know that the test grade is tomorrow, right?"
I don't like where this is heading.
"Y-yes...." He scratch his hair while looking to the other side.
"Let's make a bet."
"W-why a bet?! I don't get you sometimes." He smiled while blushing. And I think a nose bleed?!
This is going a little weird...
"If I pass the test and get a 90 or higher you'll be my maid for the whole week with no underwear. And follow everything I say!"
"Heck no!! Especially not the underwear part!" I ran to the door until Rin blocks it. "Ok, listen, when's the last time I actually had a perfect score?" He had a point though. Ever since I first got here he never had a perfect score. Which gave me an advantage. "Fine, but if I win you have to be my butler for the whole week! Without cussing your butt off on me!" Just think about it, Rin okumura, a bad boy, can't stop cussing! He won't be Rin no more, he'll be the opposite gender of Izimo!
"You got yourself a deal!" He said.
"Yup!"
