Ellie, A blonde girl with emerald eyes, suddenly appeared at my birthday banquet, proclaiming that she is father, the emperor's daughter. Father who is always expressionless and blank decided to take her in. I had been nice to her during her stay. But I still spent 70 percent of my time in my room reading novels. but suddenly I heard someone screaming and glass falling on the floor. I went downstairs to check. Then I saw Ellie, unconscious lying on the floor and beside her was a teacup shattered into pieces and her maid crying and panicking. Father quickly went out of his room then asked the maid what happened. The maid pointed he finger at me and said "Your majesty! It's lady aria! she poisoned lady Ellie's drink!". They scheduled me for execution and that day arrived. after I woke up, I realized I had been reincarnated at the novel I  read in my past life. But I'm so tired of trusting and loving people. If I let my guard down again, what happened before will repeat itself.
