The Doomed House's Contract Daughter

I thought I had regressed from this ragged life, but why has my time-limited life remained the same? I'm ruined... is this how I should live my life...? "This time, I'll get adopted by a normal family, and live in comfort for the rest of my life!" Step by step, I'm going to take revenge against the one behind my death, and I'll protect what's left of my small and precious life! However, did I put in too much effort? "Anisha, you're perfect." "I'm going to make this child a future professor." All I wanted was to survive... "Well, somehow, you’ve passed. I'll have to adopt this brat." I ended up with a tycoon I didn't expect. One whose household will be massacred in a few years! How do I know that? Me too! I didn't want to! Know that! But what can I do? The milk has already been spilt. I'll just live in bliss while acting as the real daughter during my five-year contract, then I'll leave! However... "...I happened to pick this up on the way home." "Father, you're the best!" "I know." ...Something's wrong. "I checked this out 'myself,' and inspected it 'in person.' There's nothing to be grateful for." "Father, you're a genius!" "I know this too." No, well, something's REALLY wrong. I became fond of this unique and strange family, but... "The five-year contract we signed, let's nullify it." While looking straight into my eyes, Dad announced the termination. "I can help you, but you'll still die anyway." Not only that, but death came under my nose too. Will I be able to survive?
