I don't own naruto or any character

This story sucks, BUT I AM TRYING MY BEST.

Today was a normal day in the life of sasuke uchiha. He woke up a 5 a.m to do his morning training with his best friend and brother Naruto in the old team 7 training area ( he will never say it out loud that he thinks of naruto as a brother). After 4 hours of training they took a brief brake under a tree and enjoyed the peace and silence.
-Flashback:
It was already 5 years after the great forth ninja war. Now the ninja world was safe and in piece and all of that is because of them, they were heroes, all the great nation were in debt to them. To the team seven.
After his redemption quest he came back a year ago as a new man who has a new vision, new ambitions, new resolves.
When he came back he saw in the gates the old team 7 other members. Naruto was grinning madly and joy was obvious on his face, Kakashi was now the new hokage even if his mask was covering his face that all could see that he was smiling and the last was His cherry blossom, the one that love him and care for him more than anything, the one that was always patient for him to return to them, the one that trust him and supported him threw all the mishaps in his life, she was the sun in his dark life, she was the warm feeling in this cold world for him. She was now his everything and he was in love with her.
In his travel he came to understand his feeling and acknowledge them in a practical way.
He was so happy ( even if it doesn't show on his face) when she came running for him and then hugged him soo tight like she was afraid to lose him again. Even when it was against every fibres in his body he hugged her back and whispered some words in to her ears for her to listen to them, only Her. "I am back sakura, I am home now"
She begin to cry on his shoulder, she was soooooooooooo happy, the love of her life was back 😊😊😊😊😊
- End of the flashback:
They were not a couple but to all the people that knew them, they were in love but not one of them did the first step to make it official. To Konoha she was his and his only. But he was not a lovey dovey person and she knew that but for her she was thinking that he was friendly with her because she was an ex- teammate, she wants to move on, to have a life, a person that love her and maybe a family in the future.
Sakura Haruno was ready to move on in her life and that what she was ready to do, she has a date with one of her fellow doctor. Misayi was a handsome man, very attractive, intelligent and fun to be around, he was a good friend of her and she discovered recently that he was in love with her for almost two years.
One day he sow her in deep thoughts about her relation with sasuke and that was the day she decided to move on, a single tear was falling and he sow that, he came running to her and hugged her after she explained to him the reason for her to cry he masters the strength and asked her out. A d she said yes.
What will happen to sasuke when he find out about this?
