I'm a Mighty Doomsday War God! Why Am I Bound to the Simp Heroine?

[Bickering couple + total nonsense + married first, love later + groveling to win his wife back] Jiang Lanyue, ranked number one on the list of extraordinary people, died and transmigrated. She wakes up as the hopelessly lovesick heroine of a fictional medical-consort novel, a woman who’s supposed to be adored by everyone. But this stubborn fool insists on chasing a trashy man who’s blind to the green tea schemer manipulating him, throwing herself at him endlessly before finally killing herself for love! Faced with this utterly unfriendly world and a damn System that wants to keep making her play the lovesick fool, Jiang Lanyue completely loses it! “Instead of turning all that stress inward, I’d rather go crazy and take it out on everyone else. I’ll say it again: there’s no need to act normal all the time.” “Swear out loud and your mouth gets clean. Swallow your curses, and your heart gets dirty.” “Life is like tofu pudding: sweet or savory, who cares? It all falls apart anyway.” System: “…Host, you’re out of character!” Male lead: “? Interesting.” System: “??!”
