“Finally awake?”

That’s funny. Rin didn’t realize she had opened her eyes until after the question. She slightly lifted herself up on the bed, finding herself in a hospital room. A middle-aged man in a white coat stood in front of her.

“How do you feel?” he asked.

“Ah... what happened?” Rin was puzzled.

She couldn’t remember how she ended up here. It was as if she had just been in school attending classes. Math, Literature, P.E...

“As I’m told you got hit in the chest by a soccer ball,” the doctor reported.

Right, P.E. Rin grimaced at the memory of the terrible pain in her chest. That’s when she blacked out.

“Now that Len, to kick the ball so hard,” Rin chuckled, “one could kill like that!”

“And kill you he did,” the doctor concluded. “You had a heart rupture.”

“He killed me?” Rin blinked her eyes in confusion. “But I’m not dead.”

She reached her chest. A heart was beating under the stitched scar.

“He killed you, and he also saved you,” the doctor continued. “It’s his heart.”

“But it beats the same as mine”, Rin noted. “Nothing has changed”.

“Do you understand that your brother has given his life for yours?” the doctor asked.

“I do”, Rin nodded. “I don’t understand — why? There’s no difference anyway”.

The doctor was bewildered by her attitude. There was neither joy in Rin for having been saved, no sadness for the price of that salvation. There was not even anger at her brother for making such a decision on his own, but only puzzlement as to why he had done it. Is the concept of self-sacrifice completely alien to her?

“Why don’t you ask your brother himself?” the doctor suggested.

“What, his heart?” Rin smirked. “It’s only saying: thump-thump”.

“Your brother is still hooked up to the pump. We can’t keep him like that much longer, but he requested to have one last talk to you after you wake up.”

“Well, if that’s so, then let’s go,” Rin shrugged. “I wonder what silliness he’s up to this time.”

Even the chance to say thanks or goodbye to her brother did not seem to affect her except for making her even more disoriented. As if she saw the whole situation as nonsensical.
The doctor brought Rin into Len’s room and left them alone. Len was entangled in wires and tubes leading to the medical equipment.

“Did it work?” Len was happy to see his sister.

“It did,” she replied, taking a seat on the chair next to his bed. “But why?”

“You don’t understand?” Len asked back with a sort of mischief to his smile. “Good thing they let me stay hooked up, I knew I had to explain it”.

“You better do,” Rin said. “I hope you haven’t instilled in yourself some silly sense of guilt about my death that you’re trying to atone for.”

“What are you saying?” Len replied. “We’re two parts of a whole, you and I, there can’t be any guilt between us.”

“Exactly, we’re twins,” Rin nodded. “So if one of us dies anyway, it doesn’t matter which one.”

“Look, the point isn’t which of us survives”, Len said. “The point is for the heart in the survivor’s chest to be from the other one. If it was mine that ruptured, I would have taken yours instead. Or do you mind?”

“I don’t mind, I just don’t understand the meaning of this”, Rin threw her hands up. “Without the transplantation you would have already been at home playing games, and now who knows how long they’ll be keeping me in the hospital.”

“It’s no fun to play alone,” Len pointed out, “and if one of us has the heart of the other beating inside, it’s as if we were still together. How’s that for you?”

Len looked at his sister waiting for her understanding, but got none.

“Have my death made you lose your mind?” Rin gave her brother a perplexed look. “Heart is just a pump, Len. A machine similar to the one pumping for you right now, only a biological one. Do you think there’s any of your feelings or emotions left in it? Here, see for yourself.”

Rin put her brother’s hand on her chest.

“Do you feel some kind love in there, affection?” she asked. “Do you feel how happy your heart is to become mine? No, it’s just thump-thump, thump-thump — pumping the blood. I wouldn’t have any idea it was yours if I wasn’t told so”.

“Rin, what’s gotten into you?” Len tried to interject.

“No, what’s gotten into you?” Rin countered. “Are you seriously expecting to watch over me from beyond the grave? Well, it doesn’t work like that in reality.”

“Rin, of course I’m not serious,” Len said, “I know that in reality there won’t be a me left. But then that’s only in reality. And I said that it is ‘as if’ we were still together. Like playing pretend.”

“Playing pretend?” Rin finally realized. “You mean it’s just a joke?”

“Of course it’s a joke,” Len confirmed.

Rin sighed with relief, and then burst into laughter.

“Indeed, this is so much like you,” she remarked through the laughter. “I’m dying in your arms, and your first thought is how to turn it into a joke”.

“Can’t let such a good joke go to waste”, Len smiled a mischievous smile. “Although you could have understood by yourself that I wouldn’t have seriously exchange my life for yours. I could only do that as a joke!”
The doctor entered the room, finding both twins in high spirits.

“Doctor, thank you for everything,” Rin was all glowing. “It was a wonderful joke!”

“Joke?” The doctor puzzled. “Len, you wanted to see your sister one last time... for a joke?”

“No,” Len answered, “For the joke I have given her my heart. And now I have simply explained it.”

The doctor gripped his temples with his fingers and shook his head. He should have been happy for the twins’ joy, but they were giving him a headache. It was impossible to understand them.

“Is this how you turn it off?” Rin asked without care, putting her hand to the switch on the pumping machine.

Len silently, but just as carefreely, watched his sister’s actions, as if she was just going to change a song on a player.

“Stop!” the doctor exclaimed a moment before the disaster. “Don’t do it!”

The twins had distracted him with their inscrutability, so he still hadn’t said the most important thing he’d come in for.

“A suitable heart was found, and we still have time to save Len! In a way, he bought you both time by giving his heart to Rin.”

The twins stared at each other in silence. Suddenly tears gushed from Rin’s eyes. Had she been hoarding grief inside all this time, not letting it show, and now that there was no point in it anymore, the feeling had spilled out? No, not that, the doctor realized. They were tears of joy.

The doctor sighed in relief and sat down in a chair in the corner of the room. He needed to catch his breath.

“Len!” exclaimed Rin, wrapping her brother in her arms. “Len, did you hear that? You don’t have to die now!”

“Yes,” he answered under her pressure. “Though I in partcular didn’t have to in the first place,” he grinned mischievously.

“But now neither of us have to die,” Rin continued, wiping away her tears. “We can still be together, not play pretend, but for real. Isn’t that great?”

“That’s awesome,” Len agreed. “I couldn’t even hope for such an outcome. But a miracle happened and everything worked out in the most best way possible”.

“The bestest,” Rin nodded. “It’s gonna be even funnier that way!”

And with a flick of her hand she turned off the machine that kept her brother alive. Len’s eyes bulged with shock and his mouth gaped open as if trying to say something.

“Can’t let such a good joke go to waste,” Rin said and pressed her lips to his, depriving her brother of his last words.

The kiss lasted only a moment, but when Rin pulled away, there was nothing but emptiness in Len’s eyes. Rin rejoiced. The twins loved to turn everything into a joke, and now their very existence had turned into one. After all, being twins meant being together. And now they became together not in seriousness, but as a joke. And, even better, not for the tragic reason that it was the only way for them to stay together, but as befits a joke — simply because it was funny.

“Thank you again, Doctor,” Rin said from the bottom of her new heart. “I’m so glad a heart was found for Len and his death became unnecessary.”

The doctor was still sitting on his chair in the corner utterly dumbfounded and unable to believe what was happening.

“Seriously...? You just went and killed your brother who saved your life?”

“What are you talking about?” Rin reared back. “Len is the most precious to me. I would’ve never seriously killed him. I could only do that as a joke!”

“But... why?” the doctor failed to comprehend.

Looking the doctor in the eyes Rin put her hand on her chest.

“I was following his heart,” she smiled mischievously.
