This is a Oregairu Fanfic All rights and credits go to the original author this is just purely my version of how the story will end and go.
It has been 10 years since Hachiman had seen this name appear in his email Yukinoshita Haruno. To him this name was nothing but trouble. She was the type of person who can manipulate everyone and everything on her palms without you realizing. Nonetheless he checked the email and a invitation was there. Hachiman looked at it and couldn't believe what he saw, it was a invitation to his old crush's 12 year marriage anniversary. And it said that she will be there too. He thought he forgot them and got over it after what happened a betrayal that could never be healed or forgotten. He thought he could and he did but just as he was going to reply to Haruno email and invitation and decline it knowing he doesn't want to go through the same pain again his beloved wife and most important person Hikigaya Miura previously known as Yumiko Miura. She asked, " What are you looking at." Hachiman knowing how she would respond said, " It was a email from Haruno it was a invitation to Yukino and Hayama 12 year anniversary I was gonna decline it either way because i've already gotten passed them and don't want to see them either way for what they did to me and what he did to you." Miura responded with, " Honey I think you should go and see why she invited you to begin with and don't worry about me I trust you and i've gotten past him already right now you are the most important person to me and that final okay go see what she wants but I think you should keep your occupation and status a secret." Hachiman responded with a okay and printed the invitation and started headed to the address dressed as a normal person. After the betrayal of Yukino and Yui the other person that Hachiman considered a close friend and potential love interest just like Yukinon He went down a dark path. He dropped out of college and started to be involved with yakuza activity. Even though he lost the ability to trust people in the beginning he gradually gained it back through his loyalty to companions in the yakuza and the godfather of it eventually it becoming the biggest, strongest, and most influential yakuza throughout japan. Big enough where politicians and the police will have to obey somewhat to what the yakuza says. On the deathbed of the yakuza boss he entrusted his family (side note yakuza's are normally mentioned as a family just like the mafia) to Hachiman due to his loyalty and the fact he took a bullet for him. After Hachiman inherited the Yakuza he never showed his face to the public or used his real name only going by alias like Godfather. His life took a 180 from becoming a loner, not rich, and disrespected to being respected, feared and rich. He gave his family and luxurious life and thanked them for not disowning him after he joined the yakuza.
This was just the intro and backstory of Hachiman next chapter will be about the backstory of Yumiko Miura and how she and Hachiman met and kindled their relationship to a point of marriage.
