It all started on your birthday.

You throw your birthday party at your apartment and invite all your friends and Mavros, then Mavros walks up to you and says: "You look happy tonight, huh?"

Now it's 12pm, all your friends and Mavros have gone home and you're left alone in your own apartment—a nice birthday with lots of gifts.

Suddenly there is a knock on the door, you open the door and find a strange letter accompanied by 1 red rose, the letter reads: How beautiful you look tonight, I can't wait to watch you sleeping in your bed—Tagged by M.F

while you are reading the letter, you feel like you are being stalked from a distance.
