Youngchan works at a hypermarket. He was previously diagnosed with an intellectual disability, but after a reassessment, he is no longer considered to have one. His cognitive abilities place him in a borderline range — above the threshold for disability but still below average. At first, Youngchan feels happy because he is no longer labeled as disabled. But soon, he loses his job at the hypermarket. He has trouble finding even a common part-time job and faces many challenges in life. Youngchan ends up standing at the border, constantly bumping into the boundaries.
