Five years of love and a single sentence from Lin Xia, "You have no ambition," pushed An Bufu into the rock bottom of his life. Drunk, in trouble, cut off from support, and looked down upon by the whole world, while working the night shift at the Black Tide internet café, he unexpectedly wrote a song, only for someone else to release it first and falsely accuse him of plagiarism. To win back his work, and also to prove that he is no waste, he sang his way from the corner of the internet café to the competition stage, making his ex-girlfriend cry and also touching Mai Yunjie, the girl who once scolded him as "hopeless." But when he was finally heard by the world, fate quietly pressed the countdown.
