Authors note:

I'm sorry to say that I won't be finishing this fanfic. The main reason behind this is that I didn't have a plan before I started writing this. I'm not even sure how I got the idea. When I started writing things here on I usually came up with a scene that I would love to write and therefore I built up a story around that scene, just to get it out of my head.

But I don't like how other authors give up on their stories and you never really get to know what is going to happen. Because of that I will tell you what I planned to do with the next chapter (I've actually written some kind of first scene =)

Scene 1:

They wake up together in the same bed. Yuugi prepares for school and leaves Atemu in the kitchen. Then Atemu leave and take a shortcut to school

Scene 2:

Atemu in the principal's office, he finds it a little bit hard to pretend to be a 17-year old boy and have the principal treat him as such when he used to be a mighty pharaoh.

Scene 3 (this was the scene I really wanted to write but never did):

Yuugi sits with the rest of his friends in their homeroom classroom, waiting for their teacher. They are discussing Yuugi's and Atemu's relationship (much to the embarrassment of Yuugi. Then the teacher arrives and presents the new transfer student, Sanshu Atemu. Yuugi and his friends are shocked and Atemu unfortunately get to sit on the other side of the classroom.

Scene 4:

Break. Yuugi and the others attack Atemu with questions. Yuugi is happy but wonders why Atemu kept it a secret. Atemu explains part of it. Then the bell ring and everybody have to get back to class.

Scene 5:

They had no more time to ask questions during school and now they are back at Kame Game Shop. Yuugi and Atemu have a chat. The chapter would have ended with Yuugi being angry and disappointed with Atemu.

I had already written the first scene of the chapter:

Red eyes glimmered when the light of the rising sun reflected in Atemu's eyes. He hastily cast a glance towards the alarm clock and noted that it wasn't even 6 O'clock in the morning. He wasn't really surprised that he woke up this early in the morning; it was a habit from when he was pharaoh.
"Or maybe it's because I slept for 3000 years in the millennium puzzle" he thought to himself, before resting his head against the pillow yet again. Either way he usually thought it was a waste to sleep away the day. But this morning was different. He was fully content to stay beside the sleeping boy, whose face he was gazing at with a peaceful smile.
"We must have fallen asleep as we talked last night" he reflected. He lifted his arm from Yuugi's waist and gently stroke away Yuugi's bangs from his face.
"He looks so peaceful and childlike when he asleep" he thought happily. "I could stay like this forever."
And for once, Atemu didn't get up immediately when he woke up. Instead he stayed in bed, beside Yuugi, completely content with where he was. They still had a little more than an hour before they needed to get up.
"I wonder how he'll react later today" he thought with a smile on his face, slowly drifting back to sleep.

Here is another piece that could have been worked into this part of the would be chapter:

He was lying on his side with his head resting on the pillow. He gazed at Yuugi's sleeping face, and his gaze got stuck on his aibou's pink petal lips ( this screams cliché! I'm embarrassed that I actually wrote this a year ago). Suddenly he felt the urge to kiss his aibou, and lifted his upper body, hovering over the teens face, mere inches away from his face. Suddenly Yuugi stirred in his sleep and Atemu realized what he'd been trying to do. He fell back to the pillow with a blush on his face.

So there you have it. I kind of realized that Atemu's surprise couldn't just consist of him starting at Yuugi's school. I couldn't fill this hole in the plot, because I had imagined both of the being unknowing of their real feeling for each other and every saluting I came up with only worked of Atemu had been conscious of his feeling on beforehand.
But my intention was that they would become a couple in the end (I wanted to write more fluff with them^^)

The real problem was that I didn't have a plan in the beginning. It worked for a while but then I couldn't finish it.

Thanks all of you who have read and reviewed this. I hope this is more satisfying than nothing.
