uchiha itachi

After the ten tails (on Naruto's birthday) killed your entire family, Fugaku and Mikota agreed to take you in since they were good friends with your father.
He was also an uchiha.
You and Itachi are very close, although your relationship did not resemble that of a brother and sister. More like that of best friends. Since Itachi trusts you as much as Shisui, he told you about the plan to genocide the Uchiha clan. Naturally, you were able to dissuade them from doing so (not right away).
You managed to save Shisui. Even though he lost one eye, he was able to prove to everyone what really happened.
Danzo was put in prison and Shisui's eye was returned.
(a few years later)
Itachi became the general of the Konoha police.
Sasuke went with Shisui on a very long mission (which will last 3 years).
You have become an experienced jonin.
you have sharingan, but no mangyoko sharingan. (itachi has mangyoko sharingan, because, in front of his eyes, shisui and you were seriously injured, you could have died, but itachi saved you).
There was a very dangerous gang of bandits in the city that the police couldn't catch. You finally managed to get ahead of them and expose their next plan. You and Itachi managed to arrest them, but you were badly wounded and lost consciousness.
when you woke up it turned out that you had lost your memory. Itachi was very worried about you and tried in every way to help you get your memory back. and he succeeded, but...
You realized that you fell in love with him. You didn't consider him your adopted brother, you considered him something more.
Itachi felt very guilty because you lost your memory on the mission he assigned you.
Once again after work he invited you to walk in the forest where you all loved to train together. You, Itachi, Shisui and Sasuke. There you regained most of your memory.
and then you see Itachi, who is already waiting for you at the exit:

Itachi: Good morning)
t/n: good
itachi: you're in a good mood today. did something happen?
y/n: I'm just glad you finally have time!
Itachi: I see
y/n: will you help me with training today?
Itachi: Of course I will help
t/n: thank you. then let's go to the forest? like always?
Itachi: Yeah
