Hua Manman never expected to transmigrate into a satisfying palace-intrigue novel, becoming the cannon fodder female supporting character in the book.She tried to turn the tables, but discovered that as long as she didn't act according to the plot, she would feel a heart-wrenching pain as if being stabbed by a knife.In that case, she might as well just lie flat and be a salted fish!But what was baffling was,why did that Prince Zhao, known for being sinister, ruthless, and treacherous, always like to stare at her?...Prince Zhao discovered that something seemed to be wrong with his ears.As long as he stared at someone, he could hear that person's inner thoughts.For example, right now,Hua Manman was crying with tears streaming down her beautiful face: “To be able to receive the Prince's favor is truly a blessing this humble servant has cultivated in a past life!”However, what she was thinking in her heart was—“Oh my, this chili oil today has quite a kick! It's making me cry so hard I can't even stop.”...(1v1, Sweet)

Right after transmigrating into a parallel world, Yang Yi was a bit stupefied upon seeing a adorable little girl calling him father. Fine, Xixi is 100% my daughter, but my child’s mother is actually an aloof, absolute beauty who’s a famous singer.

How do I coax my baby? Yang Yi, who was a assassin in his previous life, scratched his head. How about I tell some stories? Yang Yi didn’t think that the stories he imported from his previous world would be famous world-wide! How do I bring back my child’s mother who left in anger? The experienced Yang Yi indicated that there was no problem a love song couldn’t fix. And if it couldn’t, then two songs!
