Rebirth and Going Back to Before Being Defrauded

In her previous life, the heroine lived in a patriarchal family and lacked love since she was a child. During her internship, she met an IT engineer from the company. She was moved by his warmth and became more and more dependent on him. Unexpectedly, when she agreed to travel to Thailand with him, she was deceived by him into northern Myanmar. She was beaten to death because she did not listen to the instructions of the evil forces. When I wake up again, I have returned to the high school classroom in my previous life. Nothing has happened before. Let's see how the heroine returns in this life!
