On an ordinary summer day, Xia Yifan agrees to start dating his childhood friend Yu Yang.
Xia Yifan is thrilled. After all, the two of them had shown signs of mutual attraction back in high school, so getting together now feels like the natural next step. But on the night they submit their college applications, he has a nightmare and realizes that he is living in a scum gong novel, and that the scum gong male lead is none other than his childhood friend, Yu Yang!
In the story, Yu Yang dates him in public while secretly fooling around with one man after another: a refined but depraved teacher, the tender-hearted male neighbor next door, and a handsome senior with immense power. They all fall at his feet, captivated by his charm.
As for Xia Yifan, the "official partner," after everything comes to light, he shamelessly begs Yu Yang not to leave him, embodying the scum gong to perfection.
Xia Yifan, waking from the nightmare: As if I'd believe that. What kind of ridiculous dream is this?
But the very next second after he steps outside, he runs straight into one of the people from his dream.
Xia Yifan [shocked]: My childhood friend really is a scum gong!
Thinking of all the outrageous things his childhood friend will pull later, he immediately decides to change his college application and stay far away from that bastard.
Who could have guessed that his scum gong childhood friend would keep chasing after him? The first thing Yu Yang says is, "Baby, I want to break up."
Xia Yifan: How am I supposed to put up with that?
Yu Yang has loved his childhood friend since they were little. He has been secretly tending his little cabbage for over a decade, and after the college entrance exams, he finally gets his wish and wins his beloved's heart.
Just as he is imagining all the loving, clingy days they'll spend together in college, a breakup message extinguishes his passion in an instant.
Yu Yang can't understand why his adorable childhood friend wants to break up with him, or why he even secretly changed his college application.
Feeling wronged, he immediately buys a ticket and travels a thousand miles to win his beloved back.
As soon as he arrives, he sees his childhood friend chatting and laughing with someone else, acting intimately. Furious, Yu Yang strides up, grabs his childhood friend's hand, and shouts, "Baby, I (don't) want to break up!"
"Fanfan, listen to me. Please (don't) leave me."
"Wen Yifan, everything I just said is (not) true."
But for some reason, he just can't get the word "not" out. All he can say is that cold phrase about breaking up.
So, in front of the shocked onlookers, an enraged Xia Yifan punches him hard.
Winning his beloved back is hard. After getting beaten up over and over, Yu Yang gradually figures out the strange restriction imposed on him: he can't say the word "not" to Wen Yifan.
That isn't much of a problem. What's important is that his adorable childhood friend refuses to get back together with him and keeps calling him a scum gong.
Yu Yang is furious. He watches the refined but depraved teacher, the tender-hearted male neighbor next door, and the handsome senior with immense power circling his childhood friend, his eyes turning red with anger.
After driving away yet another man coveting his childhood friend, he finally can't help complaining to Xia Yifan: "You keep calling me a scum gong, but what's with those three!"
Xia Yifan looks at the three men beside him, each showing off like a peacock, and feels a little confused: With a setup like this, why does it feel as if I'm the scum gong (crossed out), the scum shou?
