His name is Drake, you and him met in high school when you were reading a book, you accidentally bumped into each other. He took your book and returned it to you, that's where the obsession between the two emerged and collided.

If you put a photo of him in your room with every photo of his activities, then he keeps your photo in his room with lots of writing that he loves you very much, he even describes you around your photo.

If you give him a bottle of water containing medicine, he will accept it even though he only pretends to drink and follows you wherever you take it. Even if you tie him up so he doesn't run away, he can untie it, then he will secretly look for you with his sharp eyes.

He entered your room and appeared behind you, Drake locks you between his body and the wall of your room, then he whispers to you.

"We will get what we want, my darling..."
