Best Friends Double Isekai, Twin Heirs, One Each for the Two of Us (59 episodes)

Best friends who stay up late reading novels cross over into a book together, becoming cannon fodder sister characters in an old-school angsty novel who cannot survive past three days. Su Qingruan marries the cold-faced heir Pei Wangshu, and Shen Wantang is matched with the sharp-tongued second young master Pei Wangqiao. Right at the start, they set a policy of "no romance, just survive and make money," vowing to dodge the original story's death trap. Little by little, the two of them pull off unexpected reverse-trope moves. On the wedding procession, they awkwardly run into the two male leads, which instead makes the aloof heir and the sharp-tongued young master both fall in love. A chaotic, sweet, and life-changing comedy begins to unfold.
