Note: Sorry this took so long. I've been updating Arrowverse Shipettes because I finally realized how many shipettes there are in the Arrowverse (or at least how many there could be). If you have any ships you want to be done, or want a sequel, let me know. I don't care if it's in the comments or messaged privately.

This goes out to all my fellow Little Mix fans!

I don't own the song. It's called Dear Lover.

Enjoy!

"Dear Lover,

"I love you, Len. I hope you know that. I need you to know that.

"You're probably wondering why I did it. I guess... it was just too much, you know? No. You don't know. If you did, you'd also be in a grave.

"I know you probably blame yourself. Don't. This, me being dead, isn't your fault. Plenty of people did this, or at least helped me along, but you are, or weren't, one of them. In fact, you're the only reason I lasted as long as I did.

"You're probably thinking, "Bullshit." It's not. The night I met you? After I stopped that heist, I was about ready to call quits. Really. But you struck again. I told myself I would do it afterwords, but after you got away, I decided I would wait until I caught you.

"Then I went to Jitters that one day. Remember? I do. It was the best memory I ever had. 

"You sat next to me, made conversation. I didn't take you to jail because I didn't want you to know who I was. We got to talking, and I realized that you were trying to get me to sleep with you. I almost laughed. I took you to my place, but not to have sex. To talk. I asked about private things, and I still don't know why, but you answered my questions.

"We didn't sleep together.

"Instead, I gave you my number, and we started to text each other.

"Whenever life became too much, for either of us, we would talk, or text, or meet up and make each other feel better. Eventually, I revealed that I was The Flash. You didn't care. You had gotten to know me, Barry Allen. You didn't care, and I loved you for that.

"Slowly after that, you stopped doing heists. You took the time you would have used to plan or execute them with me.

"Soon, we kissed. 

"The night of passion that followed was the best I'd ever had.

"I never wanted to give you up.

"But I would have to. After all, how could a hero and a villain be together?

"I never told anyone about our relationship. Neither did you.

"But both of our families noticed the small changes. 

"One day, they followed us. We spent that night together.

"I still remember when they busted us.

"Easily the worst moment of my life.

"We were cuddled against each other, asleep, when they walked in.

"I opened my eyes and was greeted by an angry Joe. "What the hell are you doing next to Leonard Snart!?" he had yelled. You woke up then, and stood in between me and Joe.

"I just watched in fear. What if he hurt you?

"You showed no fear as you said, "Is it against the law to cuddle with my boyfriend? Or are you just homophobic?" 

"Joe stared you down. "It is against the law when you're Leonard Snart," he said as he pulled some cuffs out of his belt.

"I couldn't believe it. "No! Joe! Please, don't do it!" I begged, but he ignored me.

"He cuffed you. I couldn't stop it. You didn't even try to.

"When I was finally alone, I sobbed. I had just lost the one thing that meant anything to me.

"And my own family had done it.

"It broke me. I didn't want to live without. Honestly, I wasn't even sure I wanted to live anymore.

"So I hung myself.

"So, Len, if you're reading this, I'm sorry I couldn't stay strong for you. I'm sorry I took the easy way out. I'm sorry I wasted your time. 

"Please don't do anything stupid. Live for me. Don't die for me.

"Finally, I didn't deserve you, but thanks. Thanks for making my final moments on this Earth worth it.

"I love you Len, and I forever will.

"I hope you love, or loved, me too.

"-Barry"

Len felt tears fill his eyes as he reread the suicide note for the fourth time.

The final time.

Then he wrote his own.

"I don't want to live without Barry. 

"Joe, you are an asshole who caused his son's death.

"Barry, I'm sorry I couldn't listen to you.

"If you're reading this, I don't know why.

"-Len"

When he was done, he grabbed a piece of rope near him and tied it to the top of his cell bars. He taped the note next to it before threading the rope through his cell.

Then he pulled the rope over his head and tied it tight.

He made a few cut off choking sounds before he saw the light.

He ran toward it.

When he got there, Barry was waiting for him.

Note: I still like The Bridge better, but this is a close second (I think).

Hope you enjoyed!
