DISCLAIMER #2: I don't own the song 'If I Knew Then'. Original ownership and credit goes to the boy, now men, band - The Backstreet Boys.

WARNING: This is a YAOI SONG-PARODY One-Shot! Don't like then don't read.

NOTE: I gained inspiration for this one shot from my teacher and Biffle, InuVampireChan~ I was reading her story 'Yami's Regret' at the same time I was listening to this song, and to me it fit perfectly. Inu-Chan, I hope you enjoy this, because this is just for you. Also, when Yami starts to listen to the lyrics alone, I strongly recommened that you listen to the song along with him to get the full understanding of what he is going through.

Me: I apologize ahead of time guys if this isn't very good. I'm still not that great at writing song parodies. Even though they make up most of my one-shot's which is sad.

Yami: *glares at me* Would you stop beating yourself up?

Me: *stares at him shocked* But...

Yami: *silence's me with a finger* You are writing it for your Biffle. I'm sure she'll love it no matter what.

Me: *sighs and moves his hand away* I hope so.

Yami: *rolls eyes then looks at the screen* Read and Review please.

If I Knew Then

Yami opened the oak door of his room that his cousin, Seto Kaiba, had let him use while he was staying with him. Once inside, he shut the door behind him, engulfing him in complete darkness before his eyes adjusted to absence of light. Leaning against the door for stability, he felt as if his legs would give out from beneath him at any moment, for not just a moment ago he had been told by his twin brother Atem and Yugi's twin, his soon to be brother-in-law, Heba that he was the father of Yugi's five year old daughter, Kairi who's sixth birthday was tomorrow. But, on the day that Yugi had found out that he was pregnant with Kairi, was the day that Yami had left him for the good for nothing whore Anzu. Taking a few deep breaths, he felt stable enough to stand without support. As he cast his crimson gaze at the floor, he pushed off from the door and wandered staggeringly over to the bed then collapsed. To any eye, it would just look as if he had fallen asleep where he stood. But, if you looked closer, you could see that his arms trembled and his body shook with rippling waves from his head to his feet, indicating that he was crying.

After a few moments of hard crying, Yami rolled over till he was flat on his back and he glared up at the dark ceiling above him. "What have I done to us Yugi?" He asked, still sobbing as he saw a faint image of Yugi and his smiling face appearing in the darkness. A smile that he had once seen so often, had now become a distant memory. How could he of been so stupid? How could he have allowed himself to be blinded by a woman that didn't even love him they way that Yugi had loved him? If only there was some way to start over again. How he wished that life was like the game of duel monsters. You make a mistake, all you had to do was shuffle the deck and start over.

"Life should be like a game of cards
You make a mistake
Shuffle the deck and start over..."

Hell, he wished that love was as easy as driving your car. If you got lost somewhere or took the wrong turn, all you had to do was activate your navigation system, type in the address, city, or location and it would guide you there or relatively close to where you needed to go without any problems or complications.

"It should be just like drivin' in your car
Get lost and your navigation system
Get's you closer..."

He side heavily as he rollled onto his side, wrapping his arm around his chest as his heart ached as the pain he felt threatened to tear him apart. "But unfortunately...there's no handbook to the game of life. You are all on your own. There are no step by step instructions to any of it. Especially when it comes to love." He sighed again as he wiped the moisture away from his eyes, he pushed up on to his elbow then sat all the way up. Letting his hand fall away from his face, he stood and walked to the closet, opened the door and flicked on the light before changing out of his regular clothes and into a white whef-beater and lose-grey sweat pants. Once he was done, he turned out the light and shut the closet door behind him, then walked back over to the bed and laid down again.

"But there ain't no handbook
You're on your own
Got no instructions
When it comes to love..."

He knew that the damage that had been inflicted on Yugi's heart, due to what he had done, couldn't be undone. For Yami had hurt him so bad that there was no way to fix it. But deep down in his heart, Yami knew that he had to try even if it did seem hopeless.

"Cause once you do something
It can't be undone..."

"I wish I could take back leaving you Yugi. I wish I could take back ever meeting Anzu, ever falling in what I thought at the time, was love with her. Then we all, you and me, could be a real family for Kairi." He sighed with a heavy heart; as he imagined what it would've been like if he had stayed. How happy they all would be right now.

"Wish I could take back
Letting you go..."

If only he knew then what he knew now. If he had known that Yugi was pregnant, he was sure he wouldn't have left him. He wouldn't have said that he didn't need him around, because he did. He always needed Yugi, and he was a fool to think otherwise.

"If I knew then
What I know now
I wouldn't of said
I don't need you around..."

Groaning as his heart gave another hard tug, he rolled over onto his side as his hand fell on the empty space beside him. He closed his eyes as he imagined how Yugi's warm body laying that has he had once done every night while they were together, and how his soft laughter used to fill the now ever growing silence in the room.

"Alone in this bed
The silence is so loud..."

"If only I had known about our daughter sooner Yugi. If only I had known before that snake of a woman sunk her fangs into me and pulled me away from you both. If only I knew, I would of treated you like gold. Yugi, my love." He said, as a tears fell down his cheeks and soaked into the plush, white pillow.

"I would treat you the best
Baby, if I knew then
What I know now..."

"I-i-i-f-f-f o-o-on-n-l-l-y I-I-I h-ha-a-d-d k-kn-n-n-o-ow-n..." He chocked out between body rattling sobs.

"What I know now (What I know now)
What I know now (What I know now)
What I know now (What I know now)..."

He heard a muffled sound coming from the radio. Slowly, he propped himself up on his left elbow and reached across the bed, grapsing the small black nob on the side of the L.E.D. screen and cranked it up a little louder so he could hear the lyrics. The song that was playing was being sung by a boy band that Yami didn't know the name of, but the words that came through the small speakers rang with truth to his situation. Wanting to listen deeply, he moved closer to the edge of the bed that was near the radio and curled up, pulling a pillow down so he could wrap his arms around it and hug it tight to his chest, wishing all the while that it was Yugi he was holding.

"Yeah I would treat you the best
Baby if I knew then
What I know now..."

His body rippled as he continued to cry, his throat and lungs burning as the air came and went in ragged, labored gasps.

"It should come with remote controls
Then I just rewind it to the time it was better..."

Yami nodded in agreement with the next few words. He wished that life had come with it's own remote control. That way he could go back to the day that he knew Yugi would be coming home to tell him the good news, to prevent ever having been with Anzu.

"It should have a restart button
So I can travel right back
To the day that I met him..."

Images of the first day that he met Yugi. The first time he heard him laugh, seen his smile, and listened to his beautiful voice. How he longed to go back to that time, so that they could fall in love all over again. Unfortunately, no tool or piece of equipment like that existed. He just had to find a way to take them back in time without actually having to physically do so. Another wave ripped through his body and he clenched the pillow tighter to his chest. He reached over and cranked the volume up and just listened to the remainder of the song, not wanting to think for hope that his heart would stop hurting and closed his eyes.

"But there ain't no handbook
You're on your own
Got no instructions
When it comes to love
Once you do something
It can't be undone
Wish I could take back
Letting you go

If I knew then
What I know now
I wouldn't of said
I don't need you around
Alone in this bed
The silence is so loud
So I would treat you the best
Baby if I knew then
What I know now

What I know now (What I know now)
What I know now (What I know now)
What I know now (What I know now)

Yeah I would treat you the best
Baby if I knew then
What I know now

Cause there ain't no handbook
You're on your own
Got no instructions
When it comes to love
See once you do something
It can't be undone
Wish I could take back
Letting you go

If I knew then
What I know now
I wouldn't of said
I don't need you around
Alone in this bed
The silence is so loud
So I would treat you the best
Baby if I knew then
What I know now

What I know now (What I know now)
What I know now (What I know now)
What I know now (What I know now)

Yeah I would treat you the best
Baby if I knew then

If I knew then
What I know now
I wouldn't of said
I don't need you around
Alone in this bed
The silence is so loud
So I would treat you the best
Baby if I knew then
What I know now

What I know now (What I know now)
What I know now (What I know now)
What I know now (What I know now)

Yeah I would treat you the best
Baby if I knew then
What I know now..."

As the song came to an end, Yami felt the air enter his chest once again. Gasping, his eyes flew open and he blinked away the tears that still threatened to escape his eyes but he fought them back. He needed to gather himself for he was going to be seeing his daughter and Yugi tomorrow and he wanted to make everything better. He wanted to fix what he could in their relationship and make it stronger. Yami knew that he had a lot of proving to do but he knew that somewhere in Yugi's heart, Yugi still loved him as much as he still loved Yugi. How strong that love was though, Yami did not know. But he was willing to take a chance and that's all that mattered.

His thoughts then trailed to the thoughts of everyone who was going to be there. How he knew that they strongly disliked him for what he had done to Yugi and their daughter, and they had every right to be cross with him. Yami didn't blame them in the slightest for he knew that it was entirely his fault that all of this had gone the way that it did. But he was going to change all of that, not matter the cost and no matter how long it was going to take.

Sighing heavily, he sat up slightly and slide his feet under the covers. Adjusting and getting comfortable, Yami glanced at the clock and read that it was now three-thirty in the morning. He only had a few hours to get some sleep before he had to get up and get ready for his little girls birthday party, the he was undoubtedly not going to miss. He took a deep breath and closed his eyes, allowing sleep to engulf him, chasing away the ache in his heart for a while.

Sorry that it's so short. I hope you guys like it.
