Yoo Ji-eun is an ordinary high school girl with a quiet nature. She prefers to stay out of the spotlight, focusing on her studies and keeping her life simple. That is, until Min-jae, a confident and charismatic transfer student, enters her life. Min-jae is everything Ji-eun is not: outgoing and naturally the center of attention. Despite their contrasting personalities, Min-jae becomes inexplicably drawn to Ji-eun’s quiet charm and begins pursuing her in his playful yet earnest way.
At first, Ji-eun finds Min-jae’s attention bothersome and tries to keep him at arm’s length. But his relentless kindness, humor, and sincerity slowly break down her walls. Over time, Ji-eun grows fond of him, and what starts as an unlikely friendship blossoms into a heartfelt romance.
However, their happiness is short-lived. As their relationship deepens, the harsh realities of their circumstances begin to emerge. Ji-eun discovers that Min-jae carries burdens of his own pressures from his family, expectations as a star athlete, and secrets he’s kept hidden from everyone. Meanwhile, Ji-eun’s own insecurities and family struggles come to light, revealing obstacles that threaten to pull them apart.
