How to Turn a Gentle Male Lead into an Obsessive Male Lead

“Noonim, you will never escape from me.” I became a supporting villain character who torments the male lead and then dies in a suspicious carriage accident. Since I was destined to exit the story without much significance beyond tormenting him with cruel words while living in the same house, I had planned to simply go with the flow, aiming only for ‘survival’… but… “You’ve inherited something bad from your mother.” “What exactly are you plotting?” The male lead, Atan Casaros, was an ominous little boy unwelcomed by everyone, and somehow, I couldn’t just stand by and watch him. “Atan, why do you live?” “…I don’t know.” “Let’s find out together.” It was partly a calculation to avoid being disliked, and partly a meddling born from sympathy. “Noonim… you can never just pass by when I’m weak, can you?” “To me, you are the most important. That’s all.” He who should have dreamed of a happy ending with the female lead, having the keyword of a ‘gentle male lead,’ “Forever and ever, I’ll hate only you, Noonim. So tell me that you’ll hate only me forever too.” He began to obsess over me. A story of struggling to change fate through all sorts of hardships, as the price for reaching out to the male lead when I only meant to change my own lifespan from the original work.
