You had a lot of time to think after your failures- no, Kaito's lucky breaks, got you kicked out of the POG. From your position as Far East Chief. Your rightful, deserved position.
You thought about puzzles that you could make, ones that would make him feel powerful sorrow and pain- ones that could end him beautifully. But you also had the time to think deeper. To remember that Kaito has never seen your face, that no matter how many times you sabotaged someone else's puzzle or nearly took his life, he still doesn't give a damn about you because he doesn't know who you are.
Next time, you wanted to meet him, face to face. You dreamed of the day. He would know the face of the person that would cause him so much suffering, he'd twinge at your name. You realized, you didn't even want to kill him. It wasn't about resolving your hatred of him. You were almost scared to think of what would happen if Kaito Daimon was no longer around for you to obsess over, to hate. You thought of him constantly. Instead, you wanted an outlet. You wanted to let him know how much you hated him, to let him know how angry you were whenever you saw his confident stare after he solved another one of your puzzles of death. You wanted him to hate you back.
You were sick of chasing after him. You would make him suffer, maybe kill one of his friends, and make him hate you as much as you hated him. He could chase after you, and you would finally be satisfied.
