Threads of Crimson and Gold

New trope (please try it, rewritten on 24.01.2024):

Micheal von Shelb, a lazy genius with a penchant for offbeat inventions, wakes up to a brutal truth: he’s a side character in a multiverse of twisted romantic dramas where his family, future children, and even his legacy are casually erased by power-hungry authors.

With Magda, his intelligent and no-nonsense wife (who’s also a supporting character in a “switched at birth” melodrama), Micheal vows to save their lives, protect their future, and rebuild the Empire through innovation and sheer audacity. Whether he's dodging political plots, perfecting horseless carriages, or making alliances with beastmen, Micheal has one goal: to carve a space where he and Magda can thrive, far from the claws of a cruel narrative.

But the fate has other plans. As ancient rivalries between archmages, devils, and mythical creatures like mermaids resurface, Micheal’s quiet dream spirals into chaos. With wit sharper than a rapier and an unstoppable resolve, Micheal proves that even a side character can rewrite the script.

Between inventing futuristic solutions and saving the day, Micheal’s true mission is impressing Magda, who may or may not be secretly stalking him from the foyer. Meanwhile, Micheal himself adjusts his routine to catch glimpses of Magda while pretending not to care.

An average day in their life:
1:00 PM: Magda: “I must be punctual to observe my husband training in the garden—from my foyer, of course.”
1:15 PM: Micheal: “Must finish the training early to sneak a peek at my wife reading in her study—from the dining hall window. Definitely not creepy.”

With its blend of humor, heartfelt romance, and action-packed multiverse chaos, Breaking the Multiverse is a read for those who enjoy clever protagonists, daring inventions, and a relationship that's equal parts banter and devotion—NO HAREM, just one unforgettable wife.

The first volume is for the general audience, the second volume is for people who prefer to sip wine as they read.
You can start reading from the second volume of you find the first volume too boring.
