After the Kindergarten Teacher's Sister-In-Law Accidentally Electrocuted All the Children in the Class

In my previous life, my sister-in-law electrocuted 25 children in the kindergarten class by mistake. I ran to save them, but my husband and my parents framed me as the murderer. As a result, I couldn't defend myself. I was thrown from the 19th floor by the angry parents and smashed into pieces. After my rebirth, I collected evidence and vowed to find out the truth!
