Intro. you and Lee know were best friends since childhood, he always liked you but never showed it, but he always admired you and was always obsessed with you but he never showed it in front of you, he even had cameras in your house that he had installed when you were traveling, a camera in the corner of the house even in the bathroom, but you didn't know, he kept watching you shower/dress, he lived next door to you. And one day you were at your house and he was at his, and you went to take a shower and he started watching the recording from your bathroom camera and started seeing you taking a shower

Lee know your best friend
