[Naruto] Dad, What Are You Doing Here?!

Hatake Sakumo never imagined that one day he would open his eyes again. Then he discovered that he had become younger and arrived several years in the future. His son had grown up, but his personality had changed completely! Not only that, but father and son had switched roles: Kakashi had become his guardian. The Uchiha Clan had been wiped out. The Third Hokage was still the Hokage. His son's teammate, Obito, the son of Hatake Sakumo's teammate Uchiha Homura, had died young. None of this could shatter the unbreakable heart of Hatake Sakumo, who had been given another chance at life. Hatake Sakumo: My heart is unbreakable! Uchiha Homura: Hello, Sakumo. I'm here too! Hatake Sakumo: ??? From then on, he lived a busy and fulfilling life, teaming up with his partner to save his son, holding his partner back from beating up his son, searching with him for his partner's son, stopping their sons from falling in love, getting their sons together, and stopping their sons from objecting to their own relationship... One-sentence summary: By a twist of fate, Hatake Sakumo and his teammate Uchiha Homura arrive in the next generation. They kick Obito's death off the table, dispel the darkness in Kakashi's heart, bring their sons together for a happy ending, and, along the way, find love themselves. Dad pairing: Sakumo x original character Homura Son pairing: Kakashi and Obito, no fixed roles
