Given in Swap, My Beggar Is Realm Lord

This is the kind of guilty-pleasure serial that knows exactly what it is. On the surface this is a Romance / Fantasy serial, but underneath it is a story about two people orbiting one inevitable collision — and "Given in Swap, My Beggar Is Realm Lord" plays both layers for all they are worth.

Sloane Whitmore is reborn moments before the wreath-throwing spouse-selection ceremony — just in time to watch her jealous sister, carrying the same past-life memories, snatch the noble match. Her answer is delinquent elegance: toss her own wreath to a ragged beggar, who is of course the supreme Sovereign of the divine realm slumming it. A rebirth duel between sisters, with the universe quietly grading one of them.

Tropes on the menu: destined love, secret crush. The pacing is relentless in the best way: no filler, just escalation.
