★ A heartfelt children’s tale about the irreplaceable magic of real friendship, even when a perfect robot friend seems like the easy fix.

★ When Yijin’s best friend pulls away, she finds comfort in Robot Seoya—who cleans, plays, and never lets her down. But as the robot’s “perfect” friendship starts to feel cold, Yijin learns that true connection is messy, flawed, and worth fighting for. This warm, relatable story helps kids navigate friendship conflicts and build the courage to reach out.

“Hello? I’m Seoya, Yijin’s friend.”
A “robot friend” appears, replacing the distant friend from before!
In the new semester, Yijin is thrilled to be in the same class as her best friend, Seoya. During every break, she wants to run over and chat with Seoya. However, Seoya barely acknowledges Yijin, always focused on tutoring homework. What’s worse, Seoya even forgets Yijin’s birthday! Yijin is furious with Seoya and coldly turns away.
Just then, Grandpa gives Yijin a very special birthday gift—a robot with human-like speech and movement abilities. Yijin decides to make the robot her friend and temporarily names it Seoya.
“Can ‘Robot Seoya’ replace the real Seoya and become Yijin’s closest friend?” “Will Seoya and Seoya (the robot) stay distant forever?” Watch as Yijin wavers between the two “Seoyas”—will her friendship ultimately find its way?

“I really wish you were here……” This is the irreplaceable meaning of precious friendship that a robot cannot understand.
Robot Seoya is a jack-of-all-trades: she skillfully cleans the room and can wake you up with dynamic music. Yijin believes that as long as the robot is by her side, she doesn’t need the real Seoya. So, whenever she encounters the real Seoya in the classroom, she treats her coldly. However, to Yijin’s surprise, the real Seoya begins to reveal precious qualities that the robot lacks…… Will Yijin eventually recognize the meaning of true friendship and gather the courage to reach out to her real friend?
This book reminds us how precious true friends are through a perfect yet cold robot—even if they have some flaws and clumsiness, they are still precious. It also tells us that building trust and communicating to seek reconciliation during conflicts is the path to healthy friendship. We hope this book will help children appreciate the value of friendship and learn how to resolve conflicts.
