[Running away while pregnant + fake siblings + both leads are each other's one and only + a little angst, lots of sweetness + “the whole world knows I love you, except you”]
Four years ago, Cheng Sang secretly became pregnant with Shen Jinghong's child and left the country to hide her pregnancy.
Four years later, desperate to get her son treated, Cheng Sang has no choice but to return and find Shen Jinghong, only to learn that he is about to get engaged to her nemesis.
Just as Cheng Sang is worrying over this, her infertile nemesis keeps knocking on her door in the middle of the night, delivering a drugged Shen Jinghong, all wrapped up and ready to go.
Cheng Sang: My crush of seven or eight years is being delivered right to my doorstep?
Nemesis: I'm just using Cheng Sang to ruin her again. She and I have a long history of bad blood, after all.
Cheng Sang: Mm, plenty of monk meat to go around.
Son: Just kiss Daddy and it'll be fine. Do you even remember you have a son?
Shen Jinghong: I don't know anything.
Until one day, everyone finds out that Cheng Sang has been secretly in love with Shen Jinghong and has his child. People feel sorry for Young Master Shen, convinced he's been played by women.
Shen Jinghong: This is so unfair, but so satisfying~
