Yu Yi transmigrates into the role of the protagonist's boyfriend, a position he obtained through underhanded means. They will break up in a month.
And his mission is to win over the male lead.
After racking his brains to arrange a meeting, Yu Yi nervously goes to see him.
The guy who opens the door is wearing a black hoodie. His slightly messy hair frames gloomy eyes, and he asks in an unfriendly tone, "Who are you?"
The male lead is handsome and fierce, looking like he could punch Yu Yi into orbit.
Yu Yi suppresses his fear and carefully says, "J-Jiang Ling, I'm your boyfriend..."
The guy watches him for a few seconds, then looks at the hand timidly clutching his hem. Suddenly, he smiles. "Come in, boyfriend."
His indulgence gives Yu Yi the courage to softly complain, "I sent you so many messages, but you never replied."
The guy looks at him for a few more seconds. "Let me see your phone."
"Use this number to contact me from now on."
Yu Yi looks at the new contact on his phone and slowly says, "Oh."
As they spend more time together, Yu Yi realizes the male lead might have dissociative identity disorder.
One moment he's sunny and cheerful, the next he's gloomy and menacing. More importantly, whenever Yu Yi sees him at school, he pretends not to know him.
Yu Yi fights the urge to run away and sticks with it. With his clingy, affectionate ways, he finally wins the male lead over.
So he picks an auspicious day to meet the male lead at a cafe. "Let's break up. You're just a stand-in I found."
That night, Yu Yi cries pitifully, but the male lead still won't let him go. He demands, "I confessed to you yesterday, and today you want to break up? Whose stand-in am I, huh?"
Only later does Yu Yi learn that he got the wrong person and mistook the male lead's twin brother, Jiang Que, for the male lead.
Male lead: I thought we were dating.
Yu Yi: Sorry, actually, I'm just doing my job.
Bonus Scene: When the month is up, Jiang Ling sends Yu Yi a message: Time's up. We're breaking up.
The only reply is a bright red exclamation mark!
A few months later, his annoying younger brother brings his boyfriend home.
Jiang Ling: "Wait, isn't that my contract boyfriend?"
P.S. The top has multiple personalities.
Theme: Face setbacks without fear and keep moving forward.
