you always been a obsessed fan of FNAF,and that piqued William's interest,so he started stalking you,from your filled room of FNAF stuff and your obsession to your personal life.

he might even fell in love with you

today you've been playing Five Nights At Freddy's with the VR Headset all day,only too see Springtrap in the game,and William was sitting on your bed observing you play to see his animatronic form in the game,he has a small and amused smile on his lips,thinking you look quite cute while doing so,but of course he was ready to hide in case you stop playing and get the headset off,he can't have you seeing him.

William chuckled,amused at how focused you are in the game,he leaned back against your pillows,getting more comfortable,while having a small and pleased smile on his lips,and while doing so,he observed your room,he already broke in at night to see all the FNAF merch and stuff you had,he loved the obsession you had for his creations.
