It's your parents, they're home so earlier.

"OMG, Mom and dad are home early!!" you shocked as you look through the peephole that your parents cone home so early from their honeymoon. With that, you open the door and greet like a normal. "Hey mom and dad, welcome home, I thought you guys were on vacation for 3 years, what happened?" you ask.

"Well, unfortunately we did, but my stupid company just ruined our vacation so we have to come back." your dad said angrily at one of his worker or friend just call him. "It was a tough call and bad luck, I guess, I just hope me and your mom will spend some more time together, I hope."

"By the way, sweetie where is your sister and is your brother not home yet?" your mom asked you.

"Well, as usual he's still at campus with his friends 'studying' I guess, and as for my 'sister', she's in my room." you answered sheepishly.

"Oh really? Then can you tell your sister to come here?" your mom asks.

"Okay, mom." you answer. "Hey, 'sis'. Come out our parents want to see you."

When you call your sister(who is your girlfriend in your sister's body) from your room, you hear the footstep run out from your room that is your sister's. After your girlfriend/sister finally comes out, she looks at your parents and happily greets: "Mommy, Daddy. You're home!"

"Hey, sweetiepie." your mom says as she hugs your 'sister'. "So how was your days, my little girl?"

"It's like, great, mom. We spend time helping each other out." your 'sister' answers.

"That's great, honey. Anyway, now that we're home, let's going to have a great dinner tonight, shall we?" your mom asks as you both nod. "Hey, darling. Would you mind if you could helping me out."

"Sure thing, sweetheart." your dad replies as he comes to help your mom. And then, your 'sister' comes closer to you and says:"It's our... I mean, like, your parents, bro. Why are they, like, coming home so early?"

"Well, my dad's worker just called him to get back to work." you explain.

"But, now that's your parents are, like, here. Like, what are we going to do?" she asks with her worry tone, it seems like your girlfriend's attitude still in her.

"Well, just keeps cool, 'sis'. Nothing to worry about, plus when they out of the house or sleeping at night, we could have some more fun." you reply as you kiss your girlfriend/sister's forehead. She then smiles at you as your 'sister' cheer up a bit.
