Genshin Impact, it's you who rejected me, why are you all in such a hurry if I just give up?

Having been reborn, Lin Jiu'an, who was a seasoned simp and love-obsessed person in his previous life and ended up with nothing, has come to a realization.
I've been reborn, and you still dare to mess with me?
Watch me kill you all!
Lick my ass, open the shark!

(Simplified synopsis: The first twenty chapters are filled with a love-struck, sadomasochistic romance; after twenty chapters, it's a bloodbath.)
(I've revised the description since it's not correct.)
(The title is also incorrect, but changing it would be too much trouble, so I'll leave it for now.)
