i’m looking for a book where the FMC works as a househelp or maid or chef through an agency. She works in different houses. One is a rich Old woman living alone. She and FMC are good friends and old woman gifts FMC a necklace. FMC also works in MMC’s house as well. Idk if she’s his househelp or maid or chef. They may have a fake relationship or something i don’t remember correctly or maybe they were falling in love with each other. then one day grandma requests FMC to go to a family dinner with her as her companion. At the dinner FMC sees MMC and he’s along with some other woman. FMC is insulted in that dinner by MMC’s family members. Later on she asks grandma if she knew who she was and grandma confesses yes she knew. In all this MMC also accuses of FMC of taking advantage of his old grandma as he thinks FMC stole her necklace. Grandma later dies in the book and leaves a letter to the FMC apologizing and explaining her side of the story. I’ve read this book but I can’t remember the title or the author. It’s driving me nuts!! Please help me find the book!!
