The Mc already dead and become a wandering soul. She got betrayed by her fiancée and an antagonist girl. Her soul sticks to the antagonist side for 5 years ( I don't remember the exact number) and witnessing how her family destroyed after her death by the one's who betrayed her. One day, she possed a dead body of a widow with a child. She found out that it is just 1 year after her death and her family haven't got destroyed. She plan to save her family, but she must transmigrate and do task to keep using the widow woman's body. So, she is doing the transmigration while making her life in reality , as a widow woman better. She is making some kind of cosmetic to make money and her product become viral. There is also the widow woman's child, he is very sensible and obedient. Mc decide to work hard to make their life better and raise this child. It's still ongoing when I read it. It's not translated (I use mtl) and I remember that I found it somewhere in the NU forum. It always has an arc about real world after each transmigration work. I actually just read some mission world ( I skipped it and just read the real world arc) and most of them have a Bad End.
