Ordinary office worker Xia Fanxing loves recording her life, but suffers from having very few likes on social media and desperately craves attention. Late at night, the Like Demon, which feeds on likes, appears from her phone and can trade traffic for her, at the cost of swallowing her true emotions bit by bit. Fanxing goes viral all the way and gains a million followers, but gradually loses her ability to feel joy, anger, sorrow, and happiness. After witnessing internet celebrity idols reduced to soulless shells, she wakes up and repents. She publicly deletes her account, and the Like Demon dissipates along with it. In the end, she lets go of her obsession with traffic, finds herself back, reaps sincere family affection, friendship, and love, and understands that happiness needs no traffic verification.
