My Last Day with Scaramouche

[Two male leads | No romance | Whether there's romantic tension is up to you] [Updates daily at 5:30 p.m.] After transmigrating into Teyvat, Sanhei accidentally becomes a student of “Teacher Hat Guy.” In class, he tries to pull off some face-slapping by confronting Scaramouche over the Raiden Gokaden, but then... Teacher Hat Guy says pensively: “So you're saying this ‘great hero's’ hatred began with Niwa's so-called ‘betrayal,’ and then spilled over onto the entire Raiden Gokaden? “Yet even after killing so many swordsmiths caught up in his rage, he spared the one person he hated most, the person he believed had started the tragedy of his life: Niwa's descendant?” Huh? That doesn't quite add up... Wait, why is this different from the game's story?! “Where exactly did I transmigrate to?!” As it turns out, this is a story about another world's “Wanderer,” set in a parallel universe. [This story differs from the plot of Genshin Impact. Some good characters from the game (no spoilers about who) will become villains in this book. If you can't accept that, please think carefully before reading. After all, novels are just for fun, so don't get mad, don't get mad.]
