I can't remember the title of this one for the life of me but the main story plot I remember involved the following points: * Female Protagonist * Possibly a transmigration novel * Not very well liked by the general public (?) * Part of a variety show * The people on the show are separated into two groups with the people joining the MC's group being rather hesitant. * MC is able to cook well while the more liked actress on the other group cooks poorly.
I'm not sure which one but, try checking The Former Wife of Invisible Wealthy Man or The Rich Ex-Husband Cries and Begs to Remarry In the first one, the MC transmigrated and she did enter a cooking variety show or some sort In the second one, the MC knew that the world she lived in was a book, in one traveling show she cooked so well
I’m not sure too but The CEO’s villainess childhood friend does fit everything other than that the variety show divided people into 3 or 4 groups.
I don’t know but you description is quite similar to this novel ( Real Missy Relies on Food to Counterattack.)
