MTL - I, Doomsday, Have Been In the Core of the Sun For a Hundred Thousand Years - Chapter 300

“Everyone deserves a happy ending, don’t they?”…In the brutal fantasy RPG Fall of Ares, saving the world came at a cruel price — the deaths of every heroine the player had grown to love. No matter how skilled you were, their sacrifices were inevitable. The game warned you not to get attached.But one young man did.After beating the game and lamenting their tragic fates, he wakes up in its world — reborn as an extra, armed with one mission from a mysterious system:[Change their endings. Let them live.]Now enrolled at Mysteria Academy alongside the heroines doomed to die, he must rewrite fate itself. For every girl he saves, he’s rewarded. But the world resists change. Calamities draw closer. The true enemy — the Children of the Sky — are watching.And one of the heroines… remembers it all.

“Did you just marry the richest man in the country… by accident? How does that even happen?”Delphinia sighed dramatically. “I know, I’m such an overachiever. But it’s easy, really. Step one: drink too much. Step two: find the perfect man. Step three: say ‘I do’ before he realizes I’m a walking disaster.”“And the revenge?”She raised her glass. “Served cold, with a diamond bigger than my ex’s ego.”—After years trapped in a loveless, abusive marriage, Delphinia had one plan: leave her toxic past behind and never look back. But freedom isn’t as sweet as she’d hoped. With no family to turn to and no place to go, she crashes with her best friend…only to end up at a party where one too many drinks lead to one tiny (accidental) marriage to Evander Walton.Handsome, rich, and absolutely off-limits, Evander is everything Delphinia thought she’d never have. And he has just one condition if she wants to break things off: she’ll have to pay him back…for the huge diamond ring she barely remembers accepting. Broke and in no position to negotiate, she’s got no choice but to play along with her accidental husband and the lavish life that comes with him.Now she’s living in luxury, holding her head high, and plotting the sweetest revenge against the ex who tried to ruin her. Because if there’s one thing Delphinia knows, it’s that payback is best served in designer heels.
