The Overpowered Hero Keeps Fighting for Everything

A Love-Obsessed, Possessive Beauty of a Dragon-Pride Protagonist 1 × A Sensitive, Delicate, Growth-Type Little Brother Bottom

[Transmigrate into a book + Two Male Leads] [Caveats] Because the author is into these things, this story contains the following:

Broken engagement / death loops / coercion / a beloved by all / dog training

Not a traditional ancient-style cultivation story, and the characters aren't perfect. Please forgive the author's shortcomings! [Both are mutually devoted and sexually exclusive, so read with confidence.]

One day, Song Mianyou transmigrates into a book as the fiancée who breaks off her engagement to the Dragon-Pride protagonist, but he doesn't know it himself.

The Dragon-Pride protagonist has a mysterious System, a harem of three thousand, and perfect beauty. Looking at that face of his, beautiful as an immortal's, Song Mianyou resolves to cling tightly to his coattails. Only, he goes about it the wrong way, and the closer he clings, the more ambiguous things become... Nobody told him the Dragon-Pride protagonist was into men and women! But that's fine too. Becoming one of the fish in the Dragon-Pride protagonist's pond is better than becoming fish food.

Then, on the day he finally makes it back from the secret realm after courting disaster at every turn, he discovers that he himself is the fiancée who showed up to break off the engagement and humiliate the Dragon-Pride protagonist. All that ambiguity seems to have been wishful thinking on his part...

Song Mianyou: “...” Why didn't you say so sooner?

In tears, Song Mianyou breaks off the engagement and says goodbye to his future life of throwing his weight around and bluffing with the Dragon-Pride protagonist's backing. Then he packs his bags and steels himself for school, ready to wait for Gu Shian, who has already enrolled under a new name and a completely new appearance, to give him a thorough taste of cultivation-world bullying.

But will someone explain why the resentful husband who sidles up to him along the way with such wicked charm is the Dragon-Pride protagonist's secret identity? And what do you mean the whole world is waiting for me to save it after I enroll?

Song Mianyou: “...” Gu Shian, step aside. You're not cut out to be the Dragon-Pride protagonist.
