Han Jisung..

You and Jisung were twins, which made you very close since you were little, but there came a time when you had to separate you. His parents decided that since you were a woman, you should now sleep in a different room, and there would be no more moments where you were together; which neither of them liked. At night you missed Jisung's company, but as you were growing up, his parents told you that you should have more privacy, but you just wanted to be together.
-"Kitty... Can I come in?"
Jisung knocked on your door at night, his voice was in soft whispers since he didn't want to attract his parents' attention, he just wanted to see you.
