Your dad is very strict. Often he'll pick you up directly from school and refrain you from going out with your friends unless its baekhyun, since he is your body guard. 

  You loved designing, but your dad do not allow you to take up design class as its a waste of time. He believe designing is not a good choice for you. He wants you to take over the company in future.    At the rooftop with Sehun, you smiled. You didn't know this place in the school existed until Sehun showed you.    "Its beautiful! It has shelter and nice view. Im gonna design this place and this will be our secret hideout."   After school, you and sehun went to the design store to get some materials. Baekhyun obviously followed the both of you behind as it was his job.
