[Sign-In System + Lighthearted Humor] The down-and-out young man Gou Fugui has no house, no car, and no steady job. Just when he has nowhere left to turn, a Sign-In System forcibly binds itself to him. One absurd mission after another appears, and the bizarre rewards are like mystery boxes. But every mission he takes brings another twist of fate. From posing for photos in a lolita outfit in the central square, to giving up his seat on the subway, to picking up rotten vegetable leaves at the market, then dancing in the square on a rainy night... Gou Fugui talks big while dying of embarrassment, gets roasted by the System, and somehow turns his fate around against all odds...
The plot is quite interesting!
