There Is Room for Returning to the 70S, and the Female Supporting Character Counterattacks and Becomes the Group Favorite

[1970S + book-wearing female supporting role + food space + food transportation system + retired military officer + group pet + female growth + business counterattack + philanthropic apotheosis] The cannon fodder female protagonist travels from the book to the 1970s, armed with a gourmet space and a system cheat. While slapping the best relatives in the face and changing their lives through counterattack, she conquers the cold-faced officer male protagonist with delicious food and raises the original protagonist's younger brother. In the end, both career and love are harvested.
