[One-on-one romance, both leads are pure, sweet pampering] Gu Ruanruan transmigrated into a book! She ended up as a background-character moonlight in the Mary Sue school romance novel The Money-Loving Sweetheart: The Scheming School Hunk's Overbearing Love, and was bound to a mission System that required her to keep the plot on track. But a bug changed the ending of the story. The male lead, who was supposed to become an overbearing CEO, went astray in high school and turned into a rich playboy.

So who was this man in her arms, crying and acting cute as he begged his wife for a hug? Boss, your character setting has collapsed!
