[Xinxie] This Son Is Definitely Not the Son of an Old Friend!

Here's the thing. On a certain day of a certain year and a certain month, when Saburo was walking unsteadily on the wall, his foot accidentally slipped and he traveled to 1582 (and after the Incident of Honnoji Temple). So—— General of the Oda family: This son looks like an old friend, he must be the son of an old friend! * The general of the Oda family who lost his friend: We will fully support you in your quest for world domination! ! But actually—— Oda Nobunaga (Hikari): I am that old friend. Oda Nobunaga (Hikari): I'm not dead yet =_= Things to know before viewing: ①This article is inspired by the Internet joke "No wonder he looks like an old friend. He turns out to be the son of an old friend. I, X, turn out to be an old friend who is still alive." But the protagonist in the article ≠ Oda Nobunaga in the article, the two are different people. In other words, this is a story about someone being mistaken for someone else's son. ②Slow update. ③The protagonist comes from the comic "Nobunaga Concerto". If you haven't read it, it won't affect your reading. I will sacrifice my own personal settings, so there will definitely be differences from the original plot. ④No CP. There is no emotional line beyond friendship or family in the whole text. It does not flirt with, marry or date anyone of the same or opposite sex. Purpose: The past cannot be changed, so we should focus on the present!
