Year 851
"Mikasa... What am I to you?"
After a moment of hesitation, Mikasa replies with a sincere tone, "Eren... You're family."
Eren, with a disappointed look on his face, says, "I see... I would have loved to spend the rest of my life with you in a remote part of Paradis. Well, let's get going, shall we? Everyone must be looking for us."
Mikasa looks shocked, and in a hurried tone, she says, "I would love to spend the rest of my life with you, Eren... I love you deeply, Eren... Please don't leave."
Eren seems shocked to hear this, almost as if he doesn't expect it, but he recovers and says, "I love you too, Mikasa... but are you certain that you want to abandon your responsibilities?"
Mikasa, with a love-filled expression, responds, "If I get to spend the rest of my life with you, then I will gladly leave all my responsibilities as a soldier."
One Month Later
In a newspaper in Paradis:
"It is reported that Eren and Mikasa have fled to some part of the world without mentioning their location in the letter addressed to Hange Zoë, the commander of the Scouts. The whole military is in chaos in a desperate attempt to find both of them."
Three Months Later
Eren and Mikasa are living in a cottage similar to the one where Mikasa lived when she was a child. It seems the cottage is near a river, as Eren has been fishing earlier.
"Mikasa, I'm back."
Mikasa tells Eren to put the basket filled to the brim with fish down on the kitchen counter so that she can cook it. While she is cooking the fish, Eren is relaxing outside on a rocking chair. It seems Mikasa has gained some weight as she has a little bump on her stomach.
Eight Months Later
It is a dark night filled with unknown tension. Only the sounds of rustling leaves and the water flowing down the river can be heard.
Mikasa's gut-wrenching screams echo through the dark night, each scream a testament to the pain and suffering of childbirth. Eren is by her side, his heart pounding as if it is about to jump out of his chest. Eren had faced countless battles and near-death scenarios, but nothing had ever terrified him as much as this—having to see Mikasa go through the pain of childbirth.
"Mikasa, hold on!!" he says, "Just a little more!!" his voice thick with emotion.
Mikasa's grip on his hand is strong—stronger than ever before, her knuckles as white as paper. Her breath comes in ragged gasps, her body exhausted from all the pain. She locks eyes with Eren; he can see the pain, the determination, and the love she has for him in her eyes.
"Mikasa, just one more push and it'll all be over. Don't give up!!"
Another wave of pain wrecks her body, and she lets out another blood-curdling scream. Eren, filled with anxiety and fear, holds her close, his heart shattering with every tear she sheds.
Then suddenly, the room falls quiet. Nothing can be heard except Mikasa's ragged breaths and the soft cries of a baby. Eren's breath catches in his throat as he looks at their child's soft and fragile hands, his emerald green eyes blinking at the world for the first time.
"Mikasa, you... did it!!" Eren reaches out to pick up their newborn. The baby's skin is warm to the touch, his fingers instinctively curling around Eren's thumb.
Tears stream down Mikasa's face as she reaches out for their child. "Eren... let me hold him..." Eren carefully gives the child to Mikasa, his heart filled with fierce love both for Mikasa and their child. As Mikasa holds her son, all her pain melts away, replaced with a profound love for her son.
"He's beautiful," Mikasa says, her voice trembling with emotion she has never felt before. "He's perfect," she adds. "Our baby boy, Eren... he's perfect."
Eren looks into her eyes, filled with love and affection. "Mikasa... have you decided on a name for him?"
Mikasa says, "Aiden," her heart filling with love and joy. "Aiden, meaning 'little fire'—a symbol of the will to fight, to survive."
Eren smiles, a tear slipping down his cheek as he says, "Aiden Yeager... it's perfect, Mikasa."
They sit there in the silence of the night, huddled together. All the uncertainty of the future seems to fade away, leaving only the warmth of their love and the beautiful life they have brought into the world.
And at that moment, as the first rays of dawn creep over the horizon, Eren and Mikasa hold on to the fragile, precious hope their son represents—a new chapter in their lives, even if only for a little while.
