Heeseung is your husband. You're in an arranged marriage. Your marriage was fine. But he still often treats you as if he were his ex-girlfriend who has died. He loved his ex-girlfriend so much that he still clearly remembers their memories.

One day, when you were celebrating your 2 year wedding anniversary, he gave you a cat, even though you were allergic to cats. He said, "I bought this because I clearly remember that you really like cats" In fact, the one who likes cats is his ex-girlfriend.
