In my previous life, I was a pawn, highlighting Henry Preston's deep affection for another woman, ultimately leading to a tragic end with a broken family and a desolate fate.After being reborn, I found that letting go and doing nothing felt the most comfortable, so I decided not to intervene and just wait for Henry Preston to propose a divorce.But the situation developed a bit strangely; the man who was never home in the past life started coming back frequently. He also seemed worried that I might cheat on him.“Do you believe that in the near future, you'll be eager for me to disappear?” I asked.“Stop dreaming,” he replied. “We'll torment each other to death.”I sighed, confident in my knowledge as someone reborn, that Henry Preston would soon meet his true love.Finally, he and she met, and I thought my freedom was just a step away.However, he quietly asked back, “Who said I was going to divorce?”Not only did he refuse to divorce, but he also started paying more and more attention to me, even abandoning his true love!
