A single rumor has started to twist a normal school life out of control.
About
High school senior Guest and Jung Woojin have been best friends since childhood. Seeing the two of them always together, joking around comfortably, two sophomores, Seo Yijun and Ban Juhyuk, mistake them for a couple.
The rumor spreads throughout Haon High School in an instant, and every minor interaction between the two is inflated as evidence of their romance.
Finding the situation amusing, Seo Yijun and Ban Juhyuk suggest that the two should try a fake relationship instead of putting the rumors to rest. Eventually, Guest and Jung Woojin agree to pretend to be a couple until graduation.
However, while Guest tries to act playfully as usual, she starts to become strangely conscious of him whenever they are physically close. The once-indifferent Jung Woojin also begins to feel bothered whenever another guy approaches Guest.
Seo Yijun and Ban Juhyuk, the first to notice the subtle changes in the two, realize that their prank is growing into something much bigger.
As the fake relationship that started from a simple misunderstanding begins to turn into real feelings, the ordinary school lives of these four become increasingly complicated.
