"He is beautiful." Levi leaned so that Raven could see the bundle of joy in his arms.
"Yes, he is."
"We made him., didn't we?"
"Of course, otouchan."
"You always break the sweet moment we have." Levi flicked Eren's forehead. Raven tiredly chuckled.
Eren winced and stuck out his tongue, "Well, you guys are always sweet 24/7. It's kind of became a habit to me."
"Eren," Raven smiled, "do you want to do the honour of naming him?"
"Fernandez. Kim Fernandez Ackerman." Eren grinned.
"Kim Fernandez Ackerman." Levi repeated.
"Kim Fernandez Ackerman." Raven repeated.
"Welcome to the family, Fernandez."
It was a year later when the family of Ackerman where able to get themselves settled down officially. Levi, of course, was still under Survey Corps as the Commander. Eren became the captain of a squad. Raven became the second general of Survey Corps under Erwin after being convinced by literally everyone. After a discussion, the Ackerman family had, they agreed to have Raven back into Survey Corps with the exception that Raven would be the brainiac to the regiment. At the very least, when there was a titan attack, they will fight alongside each other as a family that is undefeatable.
A month being back into Survey Corps, Raven found out that she was pregnant and broke the news to Levi and Eren. They celebrated in tears of joy. 9 months went by filled with crankiness, weird cravings, and a lot of demand from the general that Levi and Eren had to fulfilled. Eren even hide from his mother at times, letting his father to suffer alone. Of course, it came with a cost. Eren had cleaning duties to uphold for the rest of the year but the son did not even protest, declaring it was better than having his mother asking him to use his titan form to dance. It had been a weird 9 months yet, the family stayed together.
Today was the day, the bundle of joy came into the world. They were in euphoria. All through the years of sufferings and hard work, they made it through together as a family. Like creators of quotes said,
'Sorrow is an opportunity before happiness.'
'Life is a circle of happiness, sadness, hard times, and good times.'
'They will be time we will want to die but we persevere through the pain in agony just to know that something great will be waiting for us.'
Kim Levi Ackerman, Kim Raven Ackerman, Kim Eren Ackerman, and Kim Fernandez Ackerman lived happily ever after.
