After all the problems were solved out, Lucianos was the only problem left to solve. 

Wasting no time, Namjoon headed straight to the U.S from Germany.

Genovese's spy who walks all around the streets of San Fransisco came to know about Namjoon's arrival, and instantly let Arthur Genovese know. 

Contacting Namjoon, Arthur asked to meet him at a cafe, saying he know things about Lucianos, and Namjoon agreed to meet him. 

As Namjoon was waiting at the cafe, a black car arrived and a gentleman dressed in a black suit got out and Namjoon just knew it, that it was Arthur. 

He stood up, and they shared a handshake.

"I'm Arthur Genovese."

"Kim Namjoon," He replied with a smile, and they both sat there to talk.

"So the reason I wanted to see you is related to those guys, Jk and Jimin. Up to my knowledge, they have a boss. And I know his location, so I think it's better for you to catch the boss first. Isn't it?" Arthur asked lighting a cigar. 

Namjoon sat there speechless.

"Sir? So, you want me to lead you to their boss?" he asked with a smirk.

"We already tracked him down. Now we need the rest two." He said, 

"Stop it with your fucking lies. I know you didn't catch him just because he is your daughter's fucking husband. I know you don't have much sincerity in your work. You'd better leave Lucianos alone. In return, my men will capture two more mafia groups for you. My men will capture the Castellos and the Corleones for you. Think about it, because you tried to catch a mafia, should I expose your scandal to the outside world, or is it better to leave them alone and catch two other mafias and shine in the service?" Arthur said.

Thinking for some while, Namjoon spoke up, "Fine, I'll leave them alone."With a smirk, Arthur took out his phone and dialed for Harry, "Bring them to the cafe," he said and hung up the call. 

After some time, Harry and some other men brought the Castellos and Corleones to the cafe."Here. They're all yours," Arthur said and left. 

Leaving Castellos and Corleones there, Harry and the men also left. 

Calling other Italian soldiers for backup, Namjoon took the mafia groups to Italy. 

As soon as he reached Italy, he walked into his room, deleted all information on Lucianos, and closed their case for good. 

Before going to sleep, he took out his diary and wrote down.

Dear Diary,

Today, I did something I shouldn't have done. I put my sincerity aside for my daughter and faked my work. I am not qualified for the position I am in now. Even when I left one of the Lucianos for my daughter and went looking for the other two, I knew something was wrong with what I was doing. But I was too blind to correct it. That conversation with Arthur pointed out my mistake. I left Taehyung alone because my daughter would be worried if her husband died. But what I did was very bad. I used the power I had in my hands for my own gain. Selfishness blindfolded me. I don't deserve the position I have in this job. Tonight I decided to do two things. I am going to resign from my job as I cannot be sincere in my work. And will put aside my anger toward my daughter. There is only one life. When you die, leave no debt to anyone. 

Putting the diary away, he went to sleep. 

As for JK and Jimin, Arthur told them about Namjoon's promise and they both were free to go to Germany. 

Meanwhile, Jennie and Jk had developed feelings for each other, though they never talked about it. Soon Jimin and Jk were back in Germany. 

Lucianos' house was sold, and the fortune was divided into three. Taehyung upgraded his underwater mansion into an underwater restaurant, and they moved into his personal mansion. Jimin came back and took over the ownership of Erschaft. JK has resumed charge of Bottled Poetry.

As Jimin was back in Germany ad he got all settled, he went over to Lisa's house.

Lisa had no idea he was back in Germany.

Hearing a knock, Lisa opened the door to see Jimin standing there smiling at her.

"What!!" She couldn't believe her eyes. "Jimin? How are you- Oh my god!! I can't believe this." She hugged her tears falling from her eyes.

"I missed you so much," She said pulling away from his embrace.

"Missed you too," He said.

"But, you said you were going to surrender..." She said walking in followed by Jimin.

"Yeah, well, we didn't have to. It's a long story, and I'll tell you gradually. But right now, I wanna apologize sincerely for making you feel like you were being used. I loved you with all my heart, and I still do." He said holding her hands.

"You don't need to apologize. I do love you. Though I hate the fact that you were going to give away your life for Taehyung, I thought I hated you for that, but I could not." She said pulling him closer for a long passionate kiss.

Soon, Lisa along with Finn, moved in with Jimin to his personal mansion, as there was no point in staying at her house alone as Jisoo got married months before and had to move out with her husband.
