Three years later:

"It's your fault!" Mina gritted her teeth and tensed, squeezing Taehyung's hand tightly. "I know, princess, I know." he smiled, holding her back and hoping that while Mina gave birth to their daughter, she would not break his arm.
Taehyung tried to compare the birth to that of their son Minhoo, but he wasn't even in the room at the time because he nearly fainted in the hallway, and to stay out of trouble, he stayed at the door, crying after every scream.
"Push again, Mrs. Kim!" the doctor ordered firmly, and Mina tensed again, squirming, torn by the relentless pain. "A little more, princess!" Taehyung whispered encouragingly and wiped the sweat from her forehead with a damp towel. "I see the head!" the doctor announced, and Mina smiled wearily, straining again as another contraction tore at her body. "One more time!" the doctor ordered, and Mina gasped, trying her best to make one last effort. Relief came over her body as the baby slid and the doctor picked it up. He turned their daughter upside down and patted her ass, receiving dissatisfied loud cries from her and huge smiles from her parents.
"You did great, my love!" Taehyung kissed Mina on the forehead, and she smiled helplessly at him as she watched the doctor hand the baby to the midwife to bathe and swaddle him, and then return her clean and ready for her first meal.
"Never again!" Mina sighed wearily and closed her eyes. Taehyung smiled proudly, smoothing her hair and knowing that in just a year Mina would start insisting on another baby, just as she had done after the birth of their son.
Lily was ten, Minhoo was three, and their little daughter would be named Arzu. Taehyung felt blessed with as much happiness and luck with a wife as Mina. His dream of a big family came true thanks to her, and he kept thanking her for and showing her how much he loved her every day.
After what happened almost four years ago, their lives took a far calmer and more harmonious path. Eunji was convicted and would remain in prison for many years after he was found to have abducted and abused a pregnant woman and to kill Kaya. Eunji confessed voluntarily. It turned out that he was in the same orphanage as Mina, and that in fact Kaya had not jumped after Mina into the lake, and he had pushed her, knowing that she couldn't swim because he was jealous of her. Since then, he has not stopped following Mina, hoping that when he gets rich, she will pay attention to him. He was lucky when he was adopted by the Min family. Eunji also talked about Jung Hee, who, according to Eunji, turned out to be the serial killer of the women who matched Mina's profile. In fact, Jung Hee had chosen Mina as a model so that he could shift the blame onto his brother if he was caught. He was now unknown. There were three more murders after he disappeared, but no one had heard of him for almost two years.
Taehyung leaned back on Mina's bed, watching Arzu's already clean and happy sucking and his wife's tender smile. Now it was the turn of Namjoon and Elif, who were expecting their first child after marrying a year ago. Taehyung still couldn't believe it took Namjoon so long to propose to her. Something everyone was still teasing him about.
Jin, on the other hand, opened a salon to help newlyweds organize their weddings after organizing Namjoon and Elif's. He and his boyfriend lived and worked together. Yes, some time ago, Jin admitted that he was gay, which explained many things. After months of feeling uncomfortable around them, he soon realized that no one was impressed by his sexual orientation and introduced them to his boyfriend Adam. Who would have thought that he would live with an englishman!
Suga decided to start a regular job and hired Jungkook and Jimin, opening a private detective agency, which, by the way, was going great and the three had a hard time finding time for them, but didn't miss the weekly family gatherings Mina organized and became a tradition for them.
Hoseok began working for the Ministry of Justice. His connections ensured his continued success, and he rose rapidly, and now, with Namjoon's help, he was studying law to become a judge. Namjoon became a full partner of Taehyung and the two expanded the company, absorbing the architectural market like sharks.
"Will you take her?" Taehyung nodded and took his daughter from her mother's arms so that the sisters could move Mina to her room and clean and tidy her up. Arzu watched him with her huge black eyes as she pursed her sweet lips, as if her mother were still breastfeeding her.
He smiled at the strong grip with which the baby gripped his finger and gently pressed her, kissing the soft fluff on her head. "You look like your mother, little princess." his daughter frowned as her eyes slowly closed and she fell asleep, tired of the new world around her.
With the baby in his arms, he walked out into the hallway, where six men, a heavy pregnant woman and two children greeted him with happy screams, startling Arzu, who protested with a terrible cry that made her father laugh and immediately calmed the crowd.
"She's gorgeous, Hyung!" Jungkook stroked the baby's head in reverence, smiling tenderly at his niece. "Do you want to take her?" Taehyung asked, and Jungkook nodded timidly, taking her in, surrounded by the others who kept making funny faces or making strange cooing noises as his daughter stared at them as if wondering what aliens had attacked her. He leaned against the wall with his hands on his chest and stared at his family with a smile. Thinking that it all started with the installation of a camera and a gray mouse that shunned everyone except his daughter Lily, his heart filled with warmth and tenderness for this shy mouse that united his family even more and gave birth to two more wonderful children.
The last five years had been the happiest of his life, and he couldn't wait to see what the future held. Before he met Mina, he had no expectations of life, nor had he thought he would be eager to know what surprises tomorrow would bring. And here he is now, no less in love than on the first day, with three children, with all his friends, surrounded by happiness and love.
Taehyung left Arzu in the arms of his aunt and her uncles, and smiling at Lily, who was holding Minhoo's hand and telling him something, he headed to Mina's room to find her refreshed and slightly asleep.
"Where did you lose our daughter?" Mina smiled. "I last saw her in Hoseok's arms." he sat down on her bed and kissed her hand tenderly. "So we won't see her until at least the next meal!" Mina laughed, and Taehyung nodded in agreement, knowing that there would probably be a fight outside who to return her to her mother so that she could be fed and reassured. "I love you princess!" Taehyung intertwined their fingers. "You are my light, the star that leads me forward!" his eyes shone, full of love and adoration. "And you are mine, my love!" Mina smiled in love and sighed contentedly as he leaned over and kissed her passionately.
