Ban Christopher Chan

You are an ordinary schoolgirl who turned 15 the other day, your parents literally carry you in their arms like a piece of gold, if you want something, you will get it, but you were not spoiled, even though you were carried like a piece of gold, your parents raised you well.
Now you have summer holidays, a lot of guys are in love with you, you have beautiful blue eyes, you are a brunette, slightly fluffy hair, you have a lot of girlfriends, a lot of friends and, of course, money.
You're lying on your bed in your room at night when suddenly an anonymous person writes to you.
-Hello.
Why do you even think about answering? No, better not. A few minutes have passed and they're writing to you again.
-Why aren't you answering?
This is already stressing you out.
Ban Christopher Chan is a stalker who is following you, he knows absolutely everything about you, he saw how you change clothes, how you go to bed, how you hang out with friends, he saw all this, he is right under your nose, but alas, you do not see him and do not even suspect who he really is, he is also a maniac who wants to kill you, but also to play with you.
