I Transmigrate into a Book as an Assassin with My Love Rival: Whoever Wusses Out Is a Dog

[Transmigrate Into a Book + Alternate-Reality Republican Era + Lighthearted Comedy + Ensemble Cast]

Jiang Yu is a woman, Su Yan is a man, but the two of them have become rivals in love.

While they were arguing over which one of them was the other woman's side piece, a shoddily built structure collapsed. The two of them fell and transmigrated into an alternate-reality Republican-era novel.

They don't know the book's title or who the male and female leads are. All they know is that their characters are assassins.

Jiang Yu: "Kill someone? I can't do that. I even put 'law-abiding citizen' down as my political affiliation."

Su Yan: "Kill someone? I can't do that. I have to rely on sneak attacks when I fight."

Rivals in love become fellow countrymen, both staring at each other with watery eyes.

Together, they stumble their way through life in the Republican era.
