I Reincarnated as a Parenting Story Extra

I possessed a regular maid in a northern duke’s household in an English romance fantasy novel. A lifetime job if I just behave and do my work right? I dreamed of saving up slowly and escaping to live a peaceful life… But then— “You went to… a Korean cyber university…?” “How… how would Annie know that…?” I got caught by the main character — a reincarnated heroine from a childcare novel! Now I’ve become inseparable from the young lady who takes a deep interest in me, and even caught the attention of her older brother… “You’re quitting your job? Who gave you permission?” The childcare-novel male lead, whom I thought just noticed me, turns out to be completely obsessed! Please help! I’m just an extra! The chaotic survival story of Annie, a completely ordinary background character, in the world of a childcare romance fantasy!
