Wait I think I almost got it but can you rephrase it a little?
Do you mean an NPC who owns a potion shop and finds a book about the world she lives in, and the book has information about people/secrets/treasures? And there’s a prince + a hero who got killed by villagers? ∘ ∘ ∘ ( °ヮ° )
Also, this might be completely wrong, but could it be Trapped in a Cursed Game as an NPC? I can’t really remember anything about a book (at least at the start), but the FMC does know stuff about the game like secrets/treasures and I’m pretty sure the prince is the ML… so potion shop NPC made me think of that immediately (ᵕ—ᴗ—)
I’m so sorry about my english
But No, it’s another manga
I tried to write bullied at the end, and i do remember something about the Prince taking a liking to the Girl?. And the hero and Prince is also mentioned in the book she finds, which contain information about Them
NOOO don’t worry about your English I’m actually using a translator when I type most of my messages, so I can relate lol. (ᵕ—ᴗ—)
And ahhh okay, the “bullied hero” + manga detail helped a lot… I narrowed it down and I think I found it!! I’m pretty sure it’s I Picked This World’s Strategy Guide! ( ˶°ㅁ°)
OMG TYSM
An npc who own a option shop? Findes a book about the Worldtrade she lives in, which has information about people and their secrets and treasure aswell. There’s this Prince? And this hero who was Billie by the villaigers??
