You wake up sweating.
You know that is the dream's fault, or nightmare's fault. Nevertheless you wake up in your room. Or at least you think is your room since you still can't remember things correctly. You do remember your name so at least is not complete amnesia. So you decide to check the room. There is not much though. You only see a TV, a laptop, some books, mostly history books, and a wardrobe. There is no photos of yourself or family or anything to remind you of your past. You wonder why you don't have anything to remind of the good times you must had. Or why you could not have something of your family. You leave your room, the door is thankfully not rainbow colored like the one in your dream, and see the rest of your home.
Before anything else happens, you search for someone else in the little apartment. Of course considering that is small, it only has another room, a kitchen, a living room and the bathroom, your search ends before you get your hopes up. Which may be for the best because you didn't find anyone. The other room is empty, the kitchen is completely clean, so you either are clean freak or you don't cook, the living room is quite bland, only two sofas and a small table and the bathroom, which has supplies. Once again you don't find anything that could make you remember. And if it wasn't for the feeling that the place gives you, you could swear that this isn't your home.
A ring on the door snaps you out of your deductions. You don't know what to do now. On one hand you could open the door and wish that the person on the other side knows you, so you can ask about yourself and dispel the mystery. On the other hand, you could make the complete stranger on the other side freak out.
Another ring on the door makes you stop wondering and simply open the door.
“'Good morning Yuuno-kun.” You see a girl with short brown hair and blue eyes. While you don't remember meeting her, you know that she is slightly mischievous, and your best friend. Or something like that.
“Good morning Hayate-san.” You realize that you know her name. Yagami Hayate, who is your classmate and 'best' friend... in high school at least. You don't remember with clarity much of the time you have spent with her, but you have a general grasp on the circumstances and you hope that you remember at least half of those times together.
You hear her sigh and mutter “You always have to be so formal.” You wisely decide to ignore the comment. Suddenly she looks at you with surprise and you get nervous. There is something in how she is looking at you that makes you wonder if you did something out of your normal behavior. “Say Yuuno-kun, why are you still in pajamas? We have school today you know.”
You kind of remember that she is right. Well it does sound logical that, since she is your classmate, you need to have a class together for that to be. “Um, sorry I just woke up. Give me a second okay?” You don't wait for an answer, you kind of know what she is going to say, something like 'honestly you should not sleep so late, stop reading those books', and go to your room. You open the wardrobe and see the uniform, a red blazer and gray pants, not so bad but not that good either, and you undress and dress as soon as possible. You decide not to comb your hair, since it isn't that bad, and to skip breakfast, not knowing who you are doesn't help your appetite, so on more or less five minutes, you are ready to leave. You of course don't forget the bag with all your books. “Ready.” She smiles at you, the you-shouldn't-do-this-again smile by the way, and starts to walk away. You walk slightly behind of her, you have a vague hint of where are you going but you decide to be cautious.
The trip to the school is quiet so it lets you think about whatever is happening to you. While you still don't know much about your past, your memories have been returning. Well you think memories but it's more like feelings. Certainly you feel that Hayate is your best friend and you do know somethings about her. Not really personal stuff but her hobbies at least. And then there was the nightmare, because it can't be other thing, which didn't made sense but you get the feeling that is important somehow.
While you wondered and wondered, seriously losing your memory and having nightmares are fuel to start thinking who knew, you finally arrive at the school. While you are still confused about the whole lack of memory, you decide to act normal. Well what you think is normal anyway.
