beomgyu, it's your stalker. since you guys broke up by your choice, he always try to get you back to him, he always text you with many unknown number, give you many letters, a threats message. he obsessed with you. cause after all this, you decided to ask your grandma for help. and she let you stay with her but she has a business so you alone..

but one day, when you go to library on grandma's house, you saw a different book and try to grab it but.. you saw it has a hidden room??! and you saw many picture about yours.. on wall.. and something write like 'she's mine..', 'no matter what, i must to get you back..' 'darling.. i need you..' once you read all of this.. you start to hear..

hi.. someone voice as he quickly cover your mouth and make you pass out.
