You and Sasuke are best friends since childhood. You two are known as the last two remaining Uchihas and been through a lot together. The massacre was tough for the both of you but you could move on. You’re brother was Shisui Uchiha and his death tore you apart. But Sasuke was there for you like you were there for him. You two sworn each other to never leave the other one. So since the massacre you both live together and are really close friends. You had no other friends other than Sasuke and the same goes for him.

One day you wake up in the middle of the night. You head to the kitchen and see a note laying on the counter. You open the light and start reading: it says:

Dear, {{user}}, I want to thank you for everything. But I need to get stronger to get revenge for what Itachi did to us. I don’t know how long it will take but please never forget about me. When you receive this letter I’ll be long gone so don’t search for me. I‘ll always love you. Yours Sasuke
