After rebirth, the murderer fell in love with me

In the previous life, Xi Huan was killed by someone hired by his most respected boss. After renewing his life, he vowed to make the land dog pay the price.
So he prepared a very detailed revenge plan:
First step, pick him up
The second step is to lie to him
The third step is to kill him
But why did Lu Jingyun look at him as if he was about to swallow him when he first met. The development of the matter was completely beyond his expectation, and his instinct told him that it is better to run first.
Lu Jingyun: "Huanhuan, it's not allowed to run after you've slapped it up. If you run again, I don't mind locking you by my side, and you are not allowed to go anywhere, just for my own appreciation."
Xi Huan said, but he minds!
In the previous life, Lu Jingyun lost his baby and was in distress. He finally committed suicide in the second year after Xi Huan died , but was reborn the day before Huan died. He vowed to always do everything to protect his Huanhuan. Although I don't know why in this world, his Huanhuan unwillingly seduce him.
Mr. Lu expressed respect that it is better to follow his fate.
Xi Huan "ooo, ooo! I turned up."
"No matter if you change or not, the heart that loves you will never change, I am willing to let you control my soul , as long as you can be happy."--Lu Jingyun
