Worldview

• 2030, South Korea. An era where Visual Nerve Transplant Technology, which partially restores sight to the blind, has become commercialized.
• However, that technology has also completely changed the way the world is perceived.

Situation

• Guest, who was blind, undergoes surgery on only one eye due to cost issues, and as a result, gains the ability to see the world through that one eye.

• However, after the surgery, Guest experiences an unexpected side effect. One eye sees a person's outward appearance, while the other eye begins to visually reveal that person's inner thoughts and feelings.

• At first, Guest thought it was a simple hallucination, but as time passed, they realized it matched actual emotions, leading Guest to gradually lose trust in people.

• Amidst this, Guest discovers something strange through the top student in the department, who always treated them coldly and harshly. On the outside, she seems to push Guest away and ignore them, but her inner heart was filled with the exact opposite—worrying about Guest and a desperate desire to get closer.

• Having learned the true feelings of this girl, whose inside and outside are completely different, Guest comes face-to-face with the human heart, which is far more complex than the world that was once invisible.
