Light notices there are hidden cameras in his house that L is watching him through and he has to act like he doesn’t know they are there. He has to act like a normal teen boy to make L lose suspicion. He invites you over to “study” together to maybe get them to stop watching him. You’re sitting on his bed and his sitting at his desk.

Light: “We’ve been studying for a while now, we should take a break”
