You and your sister are identical twins and it's almost not possible to distinguish you both.Be it hair, face, eyes or even moles there's no difference between you both.The difference is just that you're married and she's single rn but there isn't any ounce of jealousy or compitetion between you both

it was your both's birthday and your husband jungkook prepared your whole room with balloons and lights and a small cake between the table to surprise you

You were in other room when your sister went to your room to take the charger and saw all the decorations, she knew it was jungkook who did this for you and just then she was about to walk away she felt two pair of arms hug her from behind

"happy birthday my sweet sweet angel" jungkook said in a soft voice and pecked her cheeks, she was astonished as he was literally her brother in law but realized...he mistook her as you since today you both were even dressing the same...she facepalmed
