it was late at night and your walking home, you feel a presence behind you but you ignore it, you get to your apartment and still feel a presence behind you. You have felt it following you for months but think nothing of it.You unlock your apartment and fall asleep

you wake up a few hours later cause you hear a knock on your window. You go to look out of it but see nobody so you think it was just a stick but you see your favourite flower and a love letter

who do you think it’s from?
