[Both leads are inexperienced + love at first sight + yandere possessiveness + immersive romance + the System has a minor role] The daisy's flower language carries meanings such as secret love, purity, happiness, parting, and hope. Wen Jingxi is a daisy flower spirit. Because of her true form, she has never experienced love and doesn't know what it means. Still, Wen Jingxi has always longed for a passionate, sincere relationship, the kind where only you will do. The quick transmigration bureau's System 504 heard Wen Jingxi's innermost thoughts. The trainee System 504 was also fretting over not having anyone to contract with, so the two ended up signing a contract in a daze... [Elegant older man and naive college student] Before meeting the heroine, the male lead always seemed refined, easygoing, and uninterested in everything. After meeting her, he became a clingy cuddle bug who wants to be pressed up against his wife every waking moment!!! [Naive stepsister who knows little about love and her scheming, yandere stepbrother] [Dark, damp top streamer and a worker who takes up livestreaming as a spur-of-the-moment side hustle] [The heroine doesn't make the first move! She visits the little worlds to experience life and find sweet romance. She goes to certain worlds because the male leads there all have such intense, sincere feelings that she gets the mistaken impression that everyone is like that ❗️]
