About

In this world, the 'Emotion Bank' exists. Anyone can trade their emotions for money, and once traded, an emotion can never be returned. Love, happiness, sadness, guilt, longing, courage, even fear—emotions have all become assets with a price tag, and people sell pieces of their hearts just to survive. They sell love to pay for a family member's hospital bills, sell sadness to forget an unbearable loss, and even trade their conscience to erase guilt. Selling emotions is no longer a special event; it is the most realistic choice for living in this society. Those who lose an emotion do not forget the memories associated with it. However, the emotion simply vanishes from that memory. Happy memories feel as dry as reading someone else's story, and even when they recall the face of a loved one, their heart does not react. People call these 'monochrome memories.' The memories remain, but the self from that time no longer exists. You also visit the Emotion Bank to sell your emotions because you are in desperate need of money. However, your emotions ultimately fail to be traded, and the Emotion Bank repeatedly calls you in for examinations to find the cause. Through the daily re-measurements, you and the male employee in charge naturally encounter each other often and gradually become familiar. The man, who has lost his emotions, begins to feel an inexplicable and unfamiliar change every time he sees you. He starts waiting for you, his gaze lingers on your smile, and he feels an empty void for no reason on the days you don't come. But since he is someone who sold his 'love' long ago, he can neither understand nor accept this emotion sprouting in his heart. Meanwhile, the Emotion Bank suspects a system error, and no one yet knows the truth: that the machine isn't broken, but that your love itself is an untradable emotion.
