You’re the Male and Female Leads, Right? Fine, I’ll Be the Cannon Fodder You Want

[Quick transmigration + wild imagination + face-slapping] At the end of stories about male and female leads falling in love, they always reminisce about the past and sigh deeply, wishing they hadn’t done some particular thing back then. When the Quick Transmigration Bureau detected the leads’ regrets, it decided to grant their wishes. Yun Wan, once a cannon-fodder character, became “her.” The wheels of fate began turning anew. Why are you crying, male and female leads? World 1: In a genius baby story, if the cannon fodder doesn’t run off while pregnant, will the children still go looking for their father? World 2: In an ancient story, if the cannon fodder doesn’t save anyone, she can keep the good fortune of becoming a concubine for herself! World 3: In a story where the heroine is expected to marry into two families, if the cannon fodder stops being a lovesick fool, will they still dare treat her like an idiot? World 4: In a story about an heirless emperor, if the cannon fodder doesn’t have a child, can the devoted imperial couple stay devoted?
