I was trying to sleep then I got a mean idea that I plan to write so hear me out.
The three characters reincarnate every time they die, they are also fated to met each other.
First Whumper meets Whumpee, who is broken and terrified because it doesn't matter what he does, Whumper will always find him and even if in another life.
And then there is Caretaker, who always find the other two too late, and most of the time can't take Whumpee away. Caretaker and Whumper are rivals/enemies everytime.
There was one life that Caretaker kidnaped Whumpee and took care of him, they lived happy years together without Whumper finding them.
However Whumper waited for the next life, in which she made sure to find Whumpee and punish him for his doings of his previous life, she punishs him so hard and brutally that Whumpee is now terrified that Caretaker may try to take him again.
