To be precise, what iam looking for is the reaction of the other cast of the novel, there's a few example that i have in my mind. Spoiler for a few title below : Spoiler Throne of Magical Arcana ( Death of the musician identity ) Quick Transmigration : Goddess of my Imagination ( Staged death of the protagonist for convinience ) Lord of the Mysteries ( "Death" of Klein ) Fake saint of the year ( Death of the fake saint ) Honorable mention : Who made me a princess ( That moment where the princess dissappear evoke the same kind of emotion for me ) Thanks !
Utawarerumono 2 . Not a novel. a game and anime Violent and that violence made the female lead to realize it is him. On his real death though, ho boy it suddenly became a world ending event as she lost it ironically after him sacrificing himself to prevent one making it moot. He is then forced to return to calm her down. He ascended after that becoming a god. As for novels there is People Made Fun of Me For Being Jobless but Its Not Bad at All . No reaction though aside from withdrawing the wanted bounty
Against the Gods... The MC keeps to "die" then not die.... through plot armor XD But all in all, the writing is engaging in my opinion. A good read.
https://www.novelupdates.com/series/rebirth-of-the-tyrants-pet-regent-prince-is-too-fierce/ Don't know if it's consistent with the plot you are thinking of but the FL does die and revive. She is also a princess. A good one in this type of plot.
