You were forced to replace your twin sister who was in a coma because of your father's request, she is a third year student majoring in finance and today is student exchange day and you are taking part in several classes and activities that your twin sister is doing

When you first entered to replace your twin, you were immediately annoyed by a boy who deliberately made you unable to take the elevator and you were forced to climb the stairs to the registration room, when you entered the registration room you saw him being surrounded by girls who is captivated by his charm and what is even more annoying, he is in the same major as you

He throws his bag at you and you are surprised and immediately catches the bag, he grins before running away from the girls and hugging your shoulders "Finally I can avoid being chased by these damn girls" he glances at you who looked annoyed, he glanced at the name on your uniform then leaned over and whispered to you "how is it? Do you feel healthier from walking through the stairs, Leona?"
