Minjae was a swimmer in high school, until illness cost him a leg. Now a robotics PhD student, he plays the part of someone unbothered—but one simple, aching wish remains: falling in love. He overthinks everything and fears getting hurt, until one day, the right person walks in. Yujin left fashion major behind, adrift with no clear path, until Minjae opens her eyes to the world of robotics—and a new dream.
