[Historical era + both leads transmigrate into a book + marriage before love + mutual secret crushes + sweet romance + devoted one-to-one couple]
When Lin Jiaxin wakes up, she has transmigrated into a novel set in the 1970s. Desperate to get back to her own world, she makes a terrible mess of things and, through a series of mishaps, marries Jiang Huaichu, the man she has secretly loved.
She treats him like a stand-in and wants him for his body. Before she can get what she wants, though, she finds herself falling for him, one step at a time.
She thinks her life has turned into a stand-in romance, only to discover that Jiang Huaichu has transmigrated into the same book, and that he had a crush on her in the real world too!
Thinking back on how arrogant she had been, Lin Jiaxin wants to move to another planet overnight.
One time, while drunk, Lin Jiaxin collapses into Jiang Huaichu’s arms and mutters, “The Jiang Huaichu outside the book is just an old man...”
Long after the incident, Jiang Huaichu asks her, “So, are you happy with your old man?”
Poor Lin Jiaxin had it rough in the real world, but inside the book, she has loving parents, a doting husband, and in-laws practically lining up to compensate her for emotional distress.
Just as she is basking in her good fortune, fate plays another trick on her…
It's beautiful and the ending is well written!
