Looking for a QT novel in which one of the arcs includes being transmigrated since childhood into a wealthy fam. Including herself, the MC was in a group of 4 childhood friends (2 boys, 2 girls).In the original storyline, the other girl(o!FL) was envious of the mc for being born in a comfortable and loving fam and eventually she discredited mc's rep in society and amongst the 2 boys(one of the 2 was the o!ML), i guess? MC's mission was to stop all the misfortunes from happening to the o!host, and the other guy( a cold genius who used to stick to the transmigrated MC since childhood) fell in love with her. Thank you to anyone who remembers and replies
