F University's two heartthrobs, Wang Guangning and Zhang Lingyi, compete in every aspect possible. From looks to talent, popularity, and even the number of their abs—they leave nothing uncompared. They even chase after the same woman. Yet, these two self-proclaimed campus Casanovas end up utterly heartbroken by her. So, they decide to take revenge on society—by pretending to be a gay couple. Using a coin toss to decide who tops and who bottoms, they agree to fake-date for 30 days, even going so far as to download *30 Things Couples Should Do Together* for a “professional” gay romance experience. For example: Watching a movie together—*Hey, bottom, could you lean on my shoulder during scary scenes?* Putting their hands in each other’s pockets for warmth—*Dude, stop wearing a military coat—it’s so embarrassing!* Two straight guys stumble through their fake relationship, creating endless mishaps under the guidance of an unreliable couple’s manual. After 30 days, the agreement ends—but can they really go back to how things were?
