Parallel Hearts (Jiang Li)

Every morning, Li Pei En wakes to the same silence - a quiet apartment, a half-empty cup of tea, and the soft ticking of a clock that never seems to move. His life runs on routine: work, exhaustion, and the calm voice of his boss, Jiang Heng - the only warmth that feels real in a world that often isn't.
Then one morning, Jiang Heng disappears. No notice. No message. Just... gone.
Days later, Pei En collapses on a rainy street and wakes to a city that looks the same but isn't. Names have changed. Faces, too. Even he himself feels different.
In this new world, his boss exists again - colder, sharper, a man who doesn't remember him. A man called Shen Weng Leng, whose scent could burn through the air.
And Pei En... is no longer himself.
Two souls. Two worlds. One bond that should never have crossed between them.
