My Parents Were Burned to Death, but My Sister Had to Accompany Her First Love to a Medical Conference.

The night her parents were set on fire, my sister was attending a medical seminar. I didn't stop her like I did in my previous life, I just calmly called the police. In my previous life, because I forced my sister to rescue my parents, I didn't let her accompany Dr. Zhou to give a speech. Later, Dr. Zhou went to present important results alone, but suffered a myocardial infarction at the venue, and rescue efforts were ineffective. After that day, my sister's whole person changed. Until I was admitted to Capital Medical College, she pretended to celebrate me and took me to the observatory to watch the stars. "Bitch! If you hadn't stopped me, how could Haochen have gone to die?" "I want you to taste what it feels like to fall from a great height!" When I fell halfway down the mountain, the admission notice was still in my arms. When I opened my eyes again, I went back to the day my parents were set on fire. In this life, I finally let my sister go to Haicheng to attend a seminar. But she went completely crazy.
