At Eighteen

At eighteen, Choi Jun Woo (Ong Seong Wu) is a perpetual loner who struggles to express his emotions, often appearing unsympathetic despite his true goofy nature. When he transfers schools, he meets Yoo Soo Bin (Kim Hyang Gi), a top student suffocated by her overbearing mother and yearning for independence. Ma Hwi Young (Shin Seung Ho) appears to be a perfect gentleman, but is actually a timid teenager searching for his place in the world. As these students navigate their individual challenges, their paths intersect, gradually transforming their lives and perspectives.
