This Nanny Is Too Arrogant

Corporate boss Sun Xiaotong hires college student nanny Liu Erya, who cares for her life in a scientific way. But Sun's mother insists on bringing in Wang Guihua, an old friend who once breastfed Sun Xiaotong, claiming she's more reliable than an outsider. Wang Guihua, relying on past favors, throws her weight around—wasting food, misusing household items, and constantly targeting Liu Erya, stealing credit, framing her, and threatening her into silence. Sun's mother favors Wang Guihua and threatens to cut ties with Sun Xiaotong, forcing Sun to let Liu Erya suffer. Wang Guihua grows more arrogant, moving her husband and son into the Sun home, where the three steal and do wrong; when Liu Erya tries to stop them, she is beaten and framed. Sun Xiaotong returns early from a business trip and catches Wang Guihua's family fleeing with the money, and finds Liu Erya locked up. Liu Erya produces video evidence, and Sun's mother repents. In the end, Sun Xiaotong calls the police to pursue accountability, apologizes to Liu Erya, and life returns to normal.
