The two have known each other since they were young and have a crush on each other. But he is a lonely ice prince, while she is an ugly duckling as calm as water; he is cold and aloof, while she is autistic and shy. In this way, they only leave incomplete fragments in each other's memories, which are both illusion and reality. He didn't know if her feelings were his illusion, and she couldn't believe whether his vow was a dream or reality. However, the two still persisted in their "love" for each other amidst the entanglement.
Just ten years later, when the two wanted to abandon that unrealistic past, they met again. The fragments of past memories suddenly became full. They wanted to tell each other their long-lasting feelings. Even if they were rejected, it was true love. After confirming the existence of each other's feelings, the two were even more ecstatic and vowed not to miss each other again. Unexpectedly, time brings not old love but a hammer that breaks the illusion. The two seem to still love each other, but the distance caused by time and family background makes them familiar strangers to each other.
The foundation of "emotion" for ten years is sad, making them unable to forget each other and love others; the fantasy of ten years is terrible, making them unable to accept the real and current each other. They have always been in unrequited love for each other, unable to let go of this unrequited love, and are deeply tortured by unrequited love. . . .
