After I Poisoned Chrollo to Death

[Third-person narration] As you can see, I'm a witch. I made a pact with Them so I could enter the human world. For 100 years, I'm not allowed to kill anyone here, or I'll be sent back. In Year 1, I met the head of the Hunters' Association. He helped me fit into this world and hired me as an outside consultant. In Year 5, the chairman and I signed a 200-year contract. I took out a loan to buy a plot of forest and live there by myself. In Year 99, I came back from gathering herbs and saw the head of the Spiders, poisoned after eating an apple. I couldn't hold back a piercing shriek. "Damn it! How can it be my fault that he ate something he shouldn't and got poisoned?!" To save the pact, I decided to bring him back to life. From then on, I had a malicious ghost haunting me. After realizing that the witch would save him no matter how hard he tried to get himself killed, Chrollo began testing her limits. He tried everything from memorizing spells and putting them into practice, to stealing the witch's powers, to tricking her into the Spider's lair just to watch her struggle to talk her way out of it. He had no idea that Lily had filled a little notebook with a long list of his unforgivable offenses. "March 1: Stole my unfinished potion." "March 5: Tried to copy my healing salve and blew up my cauldron." "April 17: Drew a demon-summoning circle under the rug." "October 10: Snooped through my notes!!!" Chrollo calmly slipped the witch's notebook into his coat. As long as he took it (stole it) fast enough, he could pretend nothing had happened. **Please note** 1. Chrollo is in his early twenties. 2. A sweet romance with a combative couple. 3. Some original additions. Theme: If you do something wrong, remember to make amends in time, or the consequences will be even worse.
