I opened the door and shut it with a thud "sisssss!!!!!!" y/n hugging me "where did you go?! Its like 8:37?!" She continued "I'm sorry,and don't such be a baby,I went..... on a friend" she looks at me suspiciously "oh,really??" She put a hand on her chin and circling me
"You changed your clothes?"
"What?! Do you think I had it?!"
"Just kidding,come on mom's waiting"
I smiled and followed her
"Mom she's here" she went to sit on the couch and turned on the TV and eat popcorn "where did you go?" she asked me "I went on friends,mom,no need to worry" she sight "S/N I need you to take charge of Y/N"
"Why?are you going to a business trip?"
"Uh....yes dear, I hope you understand,tomorrow will be my flight,I will be back in 3 weeks okay? Take care of your sister"
"But she's already old enough to take care of herself, you know"
Mom smiled and walked away then I turned to see y/n laughing I smiled and ruffled her head making her hair messy and made my way to my bedroom "hey!" I heard her shout at the background. Once I opened my door I see my window open that was near a fire escape I looked at the whole room and saw a shell near my closet I sigh and grabbed him. I knew it was Leo
"Hey" he greeted
"How did you find my house?"I asked curiously
"Did you followed me?" I added
"Uhh..kinda,yah"he replied blushing scratching the back of his head
"S/N! Who are you talking to?!" Y/n shouted and Leo went under my bed 'I hope he fits' I thought and grabbed my phone,fake calling "uh yeah sure Zoe we'll do the project tomorrow,bye"
"Oh hi y/n what are you doing here he he"
"Hmm...just suspicious...what are you hidding?"
"What?pshh nothing"
Then y/n approached the bed then she took of the sheets and looked under the bed...
