She ventured to New Joseon to safeguard him and unravel the mystery surrounding her husband's death. Upon fulfilling her purpose, she returned to Old Joseon, but her maid didn't go back ? Why , this is unclear matter. However, upon her return, she discovered she was unmarried and embarked on a mission to save her husband, ultimately succeeding. Yet, tragedy struck as he met his demise shortly after, leaving her efforts in vain. Disheartened, she returned to New Joseon and at last she came back to her love. However, the rationale behind her journey to the future and back to her present solely to uncover her husband's death secret seems questionable. Surely, she could have investigated the matter in her own time with the aid of the mystical lady. While I appreciated the storyline and commendable performances from the cast, the underlying concept of the story left much to be desired.
