On a stormy night three years ago, she found a man gravely injured in a cave. She decided to save him and on that night, in the dark, she received a marriage proposal that seemed very much like a dream—until she found out that it was in fact, very real. Three years later, they were reunited at a party. However, it had been so long since their first encounter, and they had long forgotten what the other looked like. What will happen when their deeply buried feelings resurface, and when the fragments of their memories are put together piece by piece? (Source: Bilibili Comics)
