She'd first saw it when she'd gone into his room for tutoring; the drawer of his desk which was locked. He'd told her not to go in there, that it was his diary and that it was personal, and then he'd told her to go back to homework. She hadn't even known Light kept a diary, and really, Light wasn't a secretive person by nature. He was too ideal to have any dirty little secrets, so what could he have in there? She had to know; and she just knew the answer was in that diary.It was a Friday, and she'd had a field trip that day and gotten out of school half an hour early because of it. She walked home as quickly as she could, knowing Light would be home in about fifteen minutes (his school let out earlier than hers) and she had to hurry if she wasn't going to get caught. Light would be terribly angry if he found her sneaking around in his things.She opened the door with her key, and greeted her mom in the kitchen; she went over to the counter where the silver wear drawer was located. She took a piece of fruit from the bowl to cover as she swiped a butter knife. Her mother said she was going out to the grocery store. That was good, so she wouldn't look suspicious and then passed up her room and went straight to Light's. His door was locked like she expected, but she new the ins and outs of how to open one of the locks on her door, so she was fairly confident that she could get into his. She took the butter knife she was holding and slid it in the door jam, gave a few tugs and bent the poor butter knife, but finally it opened.She opened his door and looked around, sighing at the impeccable cleanliness of everything compared to her own room. His bed was made so perfectly one could bounce a quarter off it; her blanket in her room was strewn on the floor. His hamper was hidden neatly in his closet, his dirty clothes folded in it; her clothes for the passed week were distributed directly beside her hamper.His desk held only his computer, a cup of pens and pencils, spiral notebook and a few books neatly set up beside the monitor; her desk had homework for the passed two years all over it, no pencils and one pen that had run out of ink three weeks ago which she had yet to throw away. In his closet was only ten pairs of pants and twelve shirts, one suit he wore for special occasions, and five school uniforms, all neatly hanging on wooden shouldered hangers; her closet was empty, because all her clothes were on the floor. She could rarely find a pair of matching shoes and many times got punished at school for missing a piece of her uniform because she'd lost it.She walked deeper inside his room, shutting the door gently behind her for no real reason, maybe because she was alone in the house. She tiptoed over to the desk and gripped the key –which was still in the keyhole strangely enough, as it always was –and turned it to the side, peering at the door from under her black, silky bangs, just waiting for Light to come barging in and yell at her. Sayu didn't know why she thought that he would, because Light had never yelled at her before.But then again, she'd never done something so sneaky before either.
