My Sister Murdered Her Crush's Childhood Friend

"My sister, Yvonne Jones, tried to murder the childhood friend of a rich heir in order to seduce him. Yvonne poisoned the woman's drink and pulled out her oxygen tube after she was sent to the hospital. When the rich heir arrived in a rush, Yvonne cried in his arms daintily. "I'm so sorry. This is all my fault. I failed to protect her." I witnessed everything in the ward but didn't say a word about it. In my previous lifetime, I stopped Yvonne from poisoning the woman. I knew the rich heir would never let her get away with it if he found out about it.Yvonne was forced to give up her plan and even praised me for my foresight. However, she ended up poisoning me instead and stabbed me in the heart with her dagger when I got dizzy."This is your fault! Die! If you hadn't stopped me, Sean Graham would've been mine!"When I opened my eyes next, I had returned to the day of the poisoning."
